I would like it if they reworked Doran's items. Tweak the stats around and make them 300 g like cloth armor so that there's more starting options that can potentially give you an early advantage over flask/potion spam. Idk, pots spam has really made certain lane bullies even more annoying and given formerly atrocious early laners just enough to make it to their first back easier.
League of warmog's is honestly alright with me though. I kinda like that I'm not forced into building a bunch of tanky CDR items on top laners and junglers anymore if I want to stay relevant/not get blown up. However, rushing it is pretty broken on some top laners so I think it would be great if they made it somewhat like RoA and had the health bonus increase per minute up to a cap so that you don't just rush it and instantly become unkillable. Nidalee is a good example of a champ this is a big problem with. She can just rush warmogs (**** shoes, her passive and cougar form give all the mobility she needs early on now) and push forever with her innate sustain on top of warmogs regen and cougar form trading.
That sounds similar to an old item called, what was it... oh yeah, warmogs. Riot have no idea what they are doing. You used to have to build up the HP on it just like BT.
There have been worse metas. Like those ones where 5 tanks teams where viable (Rammus Shen Malph Singed Amumu, so much fun to play against...). At least in this one every class is more or less viable. You can pick an assassin, an AP, an AD carry, a bruiser, a support or a tank, and no one is going to complain about it. But it's kind of odd, still. Potions have been around for a long time, why did people start stacking them now? Did flask do it? Or the pros just realized "yeah this is pretty good" and everyone just followed?
