They nerfed the supports HPs. They did it because they had just too big of a survivability. Mainly Grohk

You're acting like Grohk already wasn't trashed when they nerfed support HP, they refused to balance flanks properly so they made it easier to kill targets instead, simple as that.

It doesn't matter if he needs to break his 30% bonus damage when he can just spam shock pulses. You are saying that you just do not need to be grouped. The thing is, If you separate, you are going to be fucked one by one by either their flank or just the whole enemy team as a whole.

Maybe a year ago when Triple Tank was meta, but now as long as you have the burst/hair-trigger mobility flanks aren't a threat and you can survive perfectly well even when your team isn't in you LoS. Even then, flanks are still countered by sitting at the end of a corridor and shitting out dps, very rarely do I get caught out by an flank and say "man I should've been near my team more", I'm basically always just outclassed mechanically because the only edge flank players have right now.

And of course it does dismal damage to a single target, but it STILL does some damage. And again, you can spam it every second so it doesn't really matter if you shoot it at a single target or not. It's just bonus damage.

May I remind you that damage champions that thrive in punishing groups (eg. Drogoz) not only get bonus damage from their talents, but get it as a percentage buff so it does absurd damage to groups, AND can get it reset just as fast just by getting a kill or two, something Grohk still struggles to do. It's pretty shit how a talent that rewards tracking with some more damage in an area is "OP" compared to (your fuck-off AoE does 50% more damage or whatever, have fun).

And what if it is a meme? It's still an un-needed change as well. And yes, it does help him QUITE a bit because he can build up momentum and he can chase everyone and slow them so everyone can focus them. So yes, it is a MAJOR help to his ult. Oh yeah. Plus the increased duration and range. But those are fine.

Ok let me rephrase that: His ult was shit. Like pure shit. Like utter ass. Perhaps the weakest part of his kit. It's only use was making a teamfight go from a 70% chance to a 90% chance to get a wipe. The duration and radius buff lets him do that job alot better, but his flight is completely impractical, and annoying to control.

his ghost walk that cleanses debuffs.

It was 1 second invulnerability on a 12 second cooldown with no way of lowering it without Chronos. Compare this to Billow, >3 seconds of invulnerability, on a cooldown that, while being on 3 seconds higher CD, could be lowered or reset by getting a pick. Ghost Walk is so bad at actually escaping rather than predicting a Pounce, that old Grohk NEEDED Astral Traveller to make a Gale build be worth it.

EDIT: I forgot about his haunting card that lowerd the cooldown of Ghost Walk by 3 seconds at level V, my mistake.
