A good clown can kill an LK. for that matter, anyone smart enough to actually put on blue ifrit rings when dueling an LK that spams to no end has a good chance. most LK spam seeds as they spam their skill, makes them waste more seeds than you normally would've. of course if you are using a champ, that could be a problem.
Strip, isn't that actually the only chance a stalker can actually kill a champion? same with sniper. add the fact that sniper strip only really works on melee range. the removal of buffs actually made it so that not one class can kill every other class. making it a little more balanced. it's just that we don't see it, since people don't go in pvp room since they miss having their buffs. removal of every buff available makes it so that every class has a counter to it.
