solo phantasm/mag spam = strongest race
I did phantasm solo without any mag reforge and 200 ping, does that make elves strongest race? no.
What orkane said is also true.
Archery's relatively unreliable by design, and it's made worse by lag which many people cannot get around. It's hard to care how strong archery potentially is when it simply isn't working on the most basic level. With that said, I think the buff being given to it is a horrible way to try and fix a problem just like with final hit; simply throwing raw power at a mechanical problem isn't a great way to fix things.
Everything is "relatively unreliable" compared to something that's of a higher certainty. The fact that you can miss your shots at high aim % doesn't make archery less competitive than any other skillets in endgame. This is somewhat compensated with the update that allowed you to aim up to 100%, and then further remedied with this upcoming buff, to elves only, which increases the aim speed. And of course this doesn't even take into account the increased aim speed from reforges.
Everything is made worse by lag. If this lag isn't ping based (i.e. potato CPU), you really shouldn't factor this in.
