The question maybe looks silly but its real problem for me. If Im lucky and goblin will stuck somewhere (corner, some walls etc) then I can kill them without any problem and even without using big cooldowns (like bombardment on crus or wrath on barb). But most of the time they just run around so fast that I can hit them only when they stopping for a sec and later when they open portal I just dont have enough time to kill them because they are almost at 100% hp.
When I play on ranged its so easy to kill them, when Im switching to melee its just frustrating to see all this goblins just run through portal. The worst thing is when I meet goblin packs in rifts. At moments like this I just want switch to ranged and dont look back
So any advice how to kill them as melee?
