Hi!
If it's a mid rate, you should add more things to have more people. Rates are nice, I like it, but miss many basics.
Like more buffs to buffer (summons, dwarfs, improveds, noblesse, dances + songs) and a shop with more options (with items till s).
Mana potion should have reuse. 1000 recharge with 5 sec reuse would be ok.
