I haven't played many PVP games even though I'm level 30, and I have noticed that me playing support champs have given me the most success in PVP. So far, as support, I have Alistar, Blitzcrank, Lux, Lulu, Sona, Soraka, and Nunu unlocked, but I have only ever played Lulu, Sona, Soraka, and Alistar as support, and I recently bought Blitzcrank, and learning to aim his Q properly.
I have been mainly started off with Amplifying Tome + Sight Ward as the starting items on these guys, and then getting my boots of speed, and maybe another sight ward next. I then upgrade to Kage's Lucky Pick, and Boots of Lucidity/Merc Treads (depending on presence of CCs bot lane). Next, I get Philosopher's Stone, and upgrade it to Shyrelia's (spelling? >.>) Reverie asap. Of course, in between, I get sight wards and such. From there, I got Aegis of the Legion, and Soul Shroud if need be. For Alistar, I get HoG instead for the gp10 item of choice and upgrade the Amplifying Tome to Sheen instead, for the mana boost.
If that build is okay, should I just leave out the last item slot so I can get sight wards? And should I also start getting the vision wards in ALL the games, or just depending on when there's a stealth champ on the enemy team? And I'd also like to get advice on how to properly build a support if my build above is incorrect, or the order of building items is wrong, etc.
Finally, I am thinking about getting Janna as soon as I get enough IP for her (been getting runes as soon as I can afford them, since I noticed that the ones I have are why I usually lose in the first place -they suck), and I was wondering if she's one of those termed "offensive" supports, or is she also like Soraka in a sense that most of her abilities are just there to shield/heal/help bot lane in a passive way. And pretty much, an advice of her build would be very helpful as well.
And I do apologize if this is in the wrong forum, since I'm still a bit new to posting a new thread and everything ^^; (also, nearly all the actual PVPs I've played were on SR, with 3 or 4 games played in the old TT, and one in new TT -which I lost)
Thank you in advance,
P.S.: If you can refrain from using expletives while explaining why my build is wrong, or whatever, that would be much appreciated. Thank you.
