To be quite frank, I do believe ranged/mages get the short end of the stick in LoL. There has actually been suggestions as to the fact some Riot persons wanted flash removed... because it provided an escape route. In this game with so many very low CD gap closers, I don't find this trifling and pitiful; I find this a horrifying indication of what someone views as "balance".
For instance, Jax. Jax oh, Jax oh, how I hate your gap closer. It seriously has such a low CD, I seriously doubt a real "need" for the speed Ninja Tabi on Jax. It doesn't matter how fast your traveling when he has a "2 mile gap closer, with 5 second cooldown" (or whatever it is.) I could care less if they doubled his jump damage and lowered the CD!
I am happy with Trynd's gap closer, I just think he's too well rounded. I mean seriously, his Ult, plus a slow, AND a gap closer? I'd rather see him have something other than BOTH gap closing AND slow. I don't want to hear the "look back at tyrnd and it won't work imbecile". There's this thing called lag. No one plays in perfect conditions. If you do, call a scientist to investigate why your ISP is so awesome.
Akali.... similar problem to Jax imo. Except for one thing; I have burned into my memory, the following approximate values: 2200+ damage, in 2.43 seconds... Wow really?
I can't think of any other things that I think of as BS atm as far as gap closers, except for a "minor" thing with Yi; if your being chased down, your dead. He has unslowability in his ultimate. I mean sure it's supposed to be ultimate, but his Q is rather ultimate. I view his Q to be the power of an ultimate X2 when used with his actual ultimate. He becomes something like Jax or Akali, minus 50% leap, and give 50% speed. I consider speed very fair! I love speed.
I want to see more speed rather than instant gap closings. I cannot count the number of times ranged carries I played, I shot first yet because the projectiles of any sort actually take MORE time to travel that melee carries, I die first! Whether this be Ashe's ulti, Gangplank's Parley, or anything else there is. In fact, I was playing a Katarina which I almost wished to accuse of a bug because of her abuse of gameplay mechanics; she would use a gap closer, I would ulti before she reappeared or even used gap close, and she would end up behind me and use her Death Lotus.
Some of the game mechanics are outright despicable when it comes to prioritizing of things.
