i absolutely love 6.86 so far, one of my favorite patches
Wut? Over-the-top heroes are always nerfed. Usually quite hard. And right about what? As for powercreep/buffs, let's be real here, no one is guna play a dota patch with 80% nerfs and 20% +1 armor buffs. That's not exciting, that's not fun. When the shitposting/clamor for a new patch comes around it's certainly not for the 6.85 of nerfs. Most people want to see some new items, reworks, heroes, and powers/abilitiesget excited over their favorite heroes getting buffed and theorycrafting and experimenting around these new powers/buffs/items/heroes.
I don't think "powercreep" in dota is a problem at all because unlike card gamesno one gets left behind. The unpopular lower tiers are brought up and the higher tiers are brought down, sure the overall "average" power level of heroes probably increases slightly patch by patch, but again that's not a bad thing and it's counteracted by things like creep gold reductions, roshan buffs, tower buffs, more neutral camps, more base hp, etc...
I mean we went from a game that was all about 4 heroes putting up wards and standing behind the 1 hard carry as he farmed for 50 minutes into the late game where both carries would then 1v1 to see who gets to massacre the other team and take 1 tower to a game where every hero feels pretty potent and powerful and can have some measure of impact early, mid, and late (tho many still excel in one or two of the three stages)...all thanks to 'powercreep.' Playing a support is much more exciting, impactful, and fun than it was years ago because of constant buffs, new items, and QoL changes which people usually negatively refer to as 'powercreep' (which is a word often thrown out and implied to be negative by nature without actual explanation behind what's so bad or destructive about said word in the context of dota).
That nasty ol' powercreep tho; the dota apocolypse is coming cuZ of the powercreep nuclear arms race, mark my words one of these days now.
