The flaw with SW isnt mass recruiting at all, the guilds who mass recruit and get too large too quick cant generally cope with the stress that comes with it and die off a couple of weeks later so the wall is there for the taking. Exodus, too big too quick died out fast; KiS, mass recruitment from them they had about 3 weeks in their prime; TF, got a lot of KiS members but its now not as big as it used to be but granted the members they do have all have some amazing kit so are still fairly strong; FatKids, formed mainly from the exodus of TF and got very big very fast but virtually non existent now; Vendetta, had a lot of members not so long ago but now seemingly on their knees with people leaving left right and centre - these are just a few examples and the only other guild I can think of on the server atm that hasnt fallen apart at some point is Evolution.
I really dont know where people get the idea from that DA do (or ever have) mass recruited, its completely unfounded lol....
And reverance im pretty sure Evo could take the wall if they wanted - its already been proven a few times that it doesnt matter how many numbers a defending guild has when a few other guilds ally against them.
My point being, mass recruiters may take the wall, yeh, but they will inevitably disband or dramatically drop in numbers shortly after leaving it free for the next guild to take, unless there is a guild that can actually hold their crap together and keep the wall (in which case id say well deserved, reward them).
And no, I completely disagree that having a boss like MTK for the holding guild is very much game breaking reverence, I think you may be over exaggerating a little there. How many MTKs have been killed since the server started, and how many of these game breaking items that you mentioned actually dropped? I know of 1 (maybe 2) heaven armours at the moment, and thats over the space of how many months.
