I dont think so tbh you can easily earn brains to get kits through crates and its more based on pvp skill as you can get sharp 3 swords and prot 3 amour gaps power bows etc. Its just how you play against someone who donates
The ranked people get more votes on Normal, which makes the GOLD and the SILVER kit really OP in minigames (especially sw), for SBD, gkits and fly command can give a massive advantage over the other people and the ranked kits if FACTIONS are super OP, especially Immortal and all the santa, summer etc gkits in factions.
