Yes I agree but they should make a custom gun for each section the primary, melee, special and those other sections but other than that i think 1 gem for every 2nd round is fair
I think that people should be rewarded at least 2 or 3 max gems per every 5 rounds in the arena because getting gems is really hard unless you buy them or level up or wait for 10 days or however many to get gems and it takes to long.
