And just for info, the fact of volontary reduce the number of player who join the battle To volontary reduce your GP to face lower guilds and assure your victory because your 40 member who joined are still powerfull than the 50 ennemies, it's called sandbag.

There may be guilds out there doing such things and maybe they even excused for their behaviour but in all honesty i don't think that this happens every other TW to you.
The matchmaking isn't very good at all, granted. But assuming that lots of guilds are actively sandbagging doesn't seem right. If at all it may happen by accident as some people just don't can or want to participate.
