There is exactly one part of the patchnotes I find unforgivable - Exhaust now reduces attackspeed by 50%.
I hate attackspeed debuffs. They are quite literally the bane of my existence - I spend all game working on my mechanics to the point where I can precisely orbwalk without wasting any time or dps, and then BAM YOU DONE GOT ATTACKSPEED DEBUFFED SON. Not only is it a HUGE reduction in dps (well, der, a 50% reduction. I hate you multiplicative attackspeed debuffs. Also of note, 30% on top of that as 'damage reduction', so youre dealing ~35% dps), but it means it screws up my mechanics a TON. Its probably not a big deal to other people, but to me even minor attackspeed debuffs throw me off a lot.
Honestly ,other than that, I dont see much has changed. I think a lot of the melee items are different.. I am interested to see how the damage block actually plays out (5 through masteries, another 6? on dshield). I really like damage block in league, as it gives melee heros a chance to stand up against ranged heros.
I havent actually had a lot of time to play the game, mostly because I dont actually play league without my 5man team (and finalstime coming up real soon, so thats probably not going to happen much..). It looks like most of the ad carry items are the same (honorable mention to the shiv and hurricane, but like.. I am having difficulty justifying those over the standard ie/pd/lw/bt build?
