The problem is not really the powerbuilds itself, but the people creating powerbuild alts for every single purpose, like taxis etc. instead of sticking to one character.
That's why i suggest that. I hate alts, and i just want something to be more handy. I think, problem with alts, for people who dont like using alts, got something to do with no longer existing trait - Gifted.

Now its really hard to build char that dont look just like automat with one (and only one) smal bag, still kind off crapy, chips.

But the major problem with alts is just ... 21 lvl cap. But only for testing purposes and often vipeots 21lvl cap is best solution.
And i saw once a real thrower. He was preety good, but i have to kill him. But still it was a nice memory. A thrower actually fighting with throwing knifes.... Lord, You dont see something like that often in this days.
