So far my team is loving GBG. The mobile players are very excited (as they're getting the update and can play) to have something they can really take part in. We are by far the smallest guild in our match-up at 39 members (of which 37 can participate, one joined after GBG started and one hasn't unlocked Military Tactics just yet), but through teamwork and strategy we're in top position. Had to climb our way up (for a little bit we were battling for 4/5), but we did it. We're up against some active GvG guilds too, so I know they can fight. Our trick has just been getting a thread started for announcing targets, and then focusing in. Working really well so far. If we were just paired against guilds of our own size we would probably own most of the map if they weren't as active as we are. And no one is being asked to be on at all hours of the day, or stay up way too late, or anything of the sort. We're figuring out as well who is on when, and trying to plan ahead. The strategy to it is definitely subtle, but I like that. I foresee we're going to be one of the small guilds that's fighting against bigger guilds regularly, simply because our activity level is there. Attrition is a pain in the butt, but if it weren't there I think that many guilds wouldn't have a chance against the large GvG guilds (and I say this knowing that despite being in a small guild, I'm powered up more like a GvG guild and I'd be an unfair force without attrition). It definitely evens the playing field by limiting how much any player can do, and challenging what they're willing to do. There are many fighters who have too much pride to negotiate (or who focus so much on having a fighting city they don't have the goods to spare), so that's on them. GBG is definitely going to shake up some strategy on city building, and I'm okay with this. It's given some new life to our team, and I think it's going to help even the playing field for guilds who are mobile friendly to compete with GvG guilds as far as earning GP and placing in the overall rankings.
It'll be nice to see the MMR work itself out over time, because I'm really interested to know where we end up in the next few months.
