Ok,your are right to this
Think:About donations of AIO clan etc,or even about donations of +6 armor and max +8-10 weapons
if i see server max enchant is px 30 and donations are for +30 and +35 weapons i will never join...
In low rates there is kind of donations-like L2Dex which doesn't ruin the game balance
such us:Main class change(1 time)name chance,unstuck,premium acc,clan name chance,change gender
