dw is already overnerfed and some nerfs even in the wrong place. anyone still losing to him is just pitiful.
worldbreaker is still a joke without any synergy. well it s hard to create any synergy with worldbreaker abilities in the first place.
if the stun in worldbreaker was more reliable to use u could argue that it synergizes well with q built but the problem is, that to make it more reliable it needs to be faster and then there isnt enough time to prepare the breath unless there s another talent to reduce casttime on q which would be a bit too strong.
but let s take a look at possible changes for worldbreaker.
first basic attack becomes ranged and maybe a bit weaker (animation in form of spitting small fireballs maybe?)
i m not sure about what to do with lava burst. actually i think it s fine. it s a good follow up to any cc. if anything it needs more dmg from the aoezone to punish those who keep standing inside. this could be done by stacks (debuff). example: base dmg 10, 1 tick=10 dmg, 2 ticks=10+20=30dmg, 3 ticks=(10+20+30)dmg=60dmg and so on. the debuff lasts for 2/3s so it s possible to refresh it with a new cast of lava burst. i let the devs decide wether a cap is needed or not, personally i think it s not needed. brainafk’s need to be punished.
earth shatter needs more dmg for a 12s cd with such a slow travel time, but to make it not abusable against structures it should only deal 50% against those.
