Alright you can only hold one of the new weapons I have 2 of them already and I have 2 thanas <.< It sucks i've tested basically every weapon.
Champions can spam fast enough as it is as i said it is like that that you have to click 5 buttons because you get a high initial damage output, What your suggesting is like saying hey why not let sinxs have 197 aspd if you look at it through that way.
And traps are worth something you just gotta know how to use them, plus snipers have arrow repel and skid trap you can use the skid trap on your self like hunters in wow but you can do it unlimited amounts of times.
