GvG
Reduce the number of players to 30, increase resistance and HP of crystals, decrease the consumption of crystals (there are gvg that end in 3 minutes, they do not give the opposing team time to react because they have lost the 5 crystals)
TW
This is more difficult because it depends on which guilds are on each side, a serious idea on the totem map (shura in tw awak is useless), grant an aura (buff) of 50m, granting allies protection and attack to be able to retake the crystals. On the whale map, let her break the 1 hit crystal, have reflection, and instant kill.
3v3 10v10
I like the idea of changing the map, with random respawn, pet off, no charms, less time per round, the idea of a mini tw fascinated me, maybe an attack / defend the crystal in x time mode, the team that made faster wins.
TA
We only use it to collect trophies, an idea, for each victory you get 1 fragment, collecting 20 fragments you get a charm to update the trophy of choice to lvl100 with a small improvement in statistics.
MBA
Maybe implement the classic thing (I don't play this arena)
EI
I never saw this mode as pvp, they only played it for the rewards.
The rewards must be, not tradeable, furniture and pets I like the idea, titles.
Sorry for my bad english.
