If you are no-life you will have 4 21 chars within 2 days and will be bored, I agree Making 21 lvl in normal way is little harder
We had yesterday a GREAT EXAMPLE that even 21 level is too high. More than 50 players entered our little TB battle area near NCR, totally freezing and immobilizng the combat (at start it was something like 7vs9 high-lvls skirmish). But... People were returning quickly, healing themselves and there was no option to kill anybody for good, due to the high tougness, resistances, outdoorsmen and first aid. Especially, when reinforcements, allies and randoms started to come. Even Atom paid a visit into our crazy time-vortex. Whole thing took nearly 4 hours, it was a really epic and suprising event. Somebody even killed Xoen's cow. Thanks to all implicated people
If you find obvious bug/exploit to level up a character to 21 lvl in one day you should report it to GM.
THIS IS NOT BETA THIS IS SPARTA
