my suggestion :
for all balance and no try bug down lvl. maybe all char deva average lvl up to astica 21 / same for all. Not under astica 20/19.
is not confused maybe all char must lvling up to astica 21. problem done.
and problem for gm
gm must check every one by one at log file and find who the char / player to try scamm down level, if gm get a fact, maybe can give sanction/punishment.
my opinion/sugestion,. dont angry all
