We've already had 10 000 alts with different builds, before each and every wipeout. If you were playing/testing/whatever Fonline for more than three months you would know that. This is a pain in the ass for everyone except PKs (thay can easily make another superduper killing machine), radical TC PvP players (they treat the first 20 levels as a boring preparations for their beloved constant gang wars) and those like you, who don't like PvP and still don't know how it is to choose between playing 21lvl char for two months/make alts/ wait till the next wipeout.
Wait for a week. You'll understand
Before wipe, of couse I didn't had exactly 10'000 alts + 1 main so total 10'001 characters, but I had ALOT alts and no main, because they all were damned high levels, most of them deleted/remade, because I don't like to change names and use dots or minuses or other signs in names +alot test-alts with crazy builds only to testing one any thing. I tested almost everything is possible, and playing this game one year, but not 18/7 isn't means you're playing more than me total ;p Also when I downloaded that game at 28th January (fortunately, I got holidays) I didn't sleep for like 50 hours, and only then went to sleep only because I started to think that's not good, but really I didn't want to sleep, because this is the only game in the world for now worth to be played.
Of couse I can agree that lvling char to 21st is a bit... boring, but if you don't see any other aim at this game, except for "go to unguarded town and kill everything you see (for loners)" / "go to unguarded town and capture it with your gang", then of couse this is the best ever change in your life, because you can't play if your character isn't 21st level, because you'll always know that these guys in town have 21st, so they have an advantage.
