Well seeing as how there isn't really a proper board for this; I will post in Champion suggestion, because my post sort of revolves around champions and it is a suggestion.
What sets apart League of Legends from other 'DotA' games? What is going to make me want to play it? As you probably can state, the reason is, is that it is free. If you were to play DotA, you would have to spend about 30$ on the Warcraft Battlechest. If you were to play Heroes of Newerth, you would have to play a 30$ charge per account. While here at League of Legends, you could play COMPLETELY for free. Although, there is one major flaw...
The store. With it coming out yesterday, I rushed onto the computer to see what kinds of things would be available in the shop. So I log on, click on the shop and stare at a black screen for about 5 minutes, realizing that it the shop is probably really busy so I had to try again. Anyways, I was eagerly awaiting what champions I could purchase, and finally after connecting, I click on the Champion tab, and I see all the champions. I start looking at the top row. Seeing the heroes priced at 450 to 1350 IP, I was quite pleased with this, seeing is how they let us get more heroes for a bit cheaper. But upon looking at the next row, I grew increasingly angry. 6,300 IP for a champion. Or 975 riot points. I've played over 25 games and won about half of them, and I only have 3,600 IP. 6,300?!?!?!? That is ridiculously high... So I decide to check the prices of riot points. Seeing how you actually want to make money, I thought that maybe that I can buy the expensive heroes with riot points, because there probably is some discount or advantage.
But was there? NO! There wasn't. They expected me to pay about 8-10$ for ONE champion!? JUST ONE. Karthus, Anivia, Corki, Blitzcrank, and Twitch cost 6,300 IP or 8-10$ for EACH ONE. Well were never seeing these guys in our matches again....unless some people save up all their IP and that is the only hero they actually unlock.
Alternatively, we can buy the collectors edition for 30$ (includes a 10$ riot point card), and then buy the champion bundle for the other 20 champions for 25$, but that really defeats the purpose. Lets do some basic math, shall we?
30$ + 25$ = 55$, You could argue 45$ because there is a 10$ gift card, but the fact of the matter is you still have to dish out 55$.
30$ - You could buy Warcraft 3 and play DotA. While you'd be missing out on some of the great changes here in League of Legends, you at least get all the content and you don't have to worry about dishing out 10$ for the new hero...
30$ - You could buy Heroes of Newerth. This is where your competition lies, Riot. Warcraft 3 is getting old and the server structure sucks. You and HoN are the 'new versions' of DotA that are trying to capture both the DotA audience and some new audiences. You both offer great new features to an outdated game that make it something desirable again. While I'll argue that League of Legends is the better game here, I have been debating between the two games for quite awhile now. I can pay 25$ less for an included VoIP system, and all the content unlocked.
Now my suggestion...
I suggest you make your prices a bit more fair. Charging almost 10$ for a champion is ridiculous. We will rarely see these Champions in play. The only people who will have them are the people who bought either the 30$ pack, the 25$ pack, or both, because no one in their right mind would play 60 games for just ONE champion, or pay 10$ for ONE champion.
A second point: Since we have to pay to unlock our Champions, it creates an imbalance. With games of this type, their is a fairly large and extensive set of playable characters. 40 here in LoL, 90-some in DotA, and somewhere in between in HoN. This creates for diverse game play and new experiences each time.
However, with such a system with an extremely expensive shop, you are limiting your game to the 10 heroes that are free that week. Every game will have nearly the same heroes as the next. While people will play with the heroes that they have bought, lets say they bought Heimerdinger, playing with one champion gets old after a 5-6 games. Its always nice to switch to another. However since they spent 3k on that champion, they are less likely to have many other heroes unlocked. Resulting in repetitive, non-diverse, game play, because their options probably consist of one or two other heroes, and the weekly free set.
Please, I'd hate to see such an awesome game just go wrong because of an expensive shop. I only ask that you re-balance the shop. If anyone has already made a purchase to a re-balanced price, refund them or offer something in return so they don't get angry either.
Closing, please take this into consideration, I understand that this is a lot to take in or is probably a large problem to fix, but if it were fixed, this game would be all that much better.
