and although the latest "fortress" tournament may appear great at first, it's just a quick bandaid, certainly not a definitive solution.
"yeah look, we can win 8000 tomes!!" but a level 8 bonus will need 25600 tomes. and a level 10, 102 400 tomes. and level 15, 3 276 800 tomes.
the way to fix this is NOT by giving out tomes rewards, either you won't give enough to reach higher levels, or you'll give too many and every one will have all bonuses up to level 10 in no time!
the whole thing should be taken back to the drawing board, (re?)thought out, but of course, that is just not going to happen...
