this suggestion is good but make it 10v10 only and it will be good because 20v20,30v30 its too much and it might ruin pk harmony :-Xl
We tried few times to make House of War (similar event, GvG 10vs10) alive and basically none faction other than Xpendable was willing to participate. Also like 2 weeks ago when ET wanted to make 10vs10 for free ECs coming from XP, none faction was willing to participate either. As long as making 5v5 (let's say, or similar numbers) may work, I doubt anything that would require more ppl in teams, will work. And about 5v5/6v6/4v4 but only faction members, there is already suggestion which we gonna look into it but tbh I doubt we can get more than 3-4 factions willing to do that (participate in such event). Sometimes it's hard enough for us to collect 8 teams fo events like 4v4/5v5 where you don't have to belong to X faction in order to make a team. Or for events like CtF / Keep Away we quite often have to make teams by ourselves (by picking ppl who pms us).
I have to totally agree on to that. But maybe we can try abit more this time ? with better prizes and give them time to prepare their guild ? ;o
