I don't know why everyone is playing sic'em dps rangers in solo queues so not as much attention is brought up in regards to this monster. It's another one of those overtuned bunkers brusiers that is both difficult to kill and does high damage. In my opinion, it is a tier above all other bunkers (including meta spellbreakers & holos) because it has all these things listed below.
As if spamming boons isn't enough, it's also allowed to spam a bunch of condis for some reason, namely these OP ones with basically 24/7 uptime:
1. Weakness -- kills all power builds and reduce opponent's endurance, so less dodges
2. Chill -- good against everyone really
3. Poison -- significantly reduce opponent's sustain while doing damage.
I can't think of any other bunker builds has access to all 3 of these condis to turn the fight greatly in their favor, not with that high of an uptime anyways.
This build needs to be nerfed before everything else in my opinion. It doesn't have any losing 1v1s, has no trouble 1v2, and can survive 1v3 for a decent amount of time if you play well, similar to how bunker druids were before. I am not sure what counters it other than outnumbering it (i.e. 2v1/3v1) with a boon corrput necro or a good sw/d thief that can land their boon steals + burst it while not getting caught up in ccs himself. It's also not completely useless in teamfights when it can show up to one and burst people with axe5/one wolf pack or just spam its bouncing axe autos, share boons/stances, and stack condis.
And fix the extra duration bug on Lesser Muddy Terrain already. It's ~17s currently which means near perma uptime if you just trait your heal skills to be 20s cd. In fact, I dont even know why that trait has a 10s duration as its default considering how it covers most of the entire capture point and pulses kitten slow and cripple for that long. It should really be nerfed down to <5s like all other on heal skills.
