The number of TW teams per zone should be based on the guild with more players participating. Currently, each zone requires a number of teams equal to half the number of participating players for the guild with the lower number of players in the TW. For example, we had 49/50 join and have an active GP of approximately 164 mil. Our opponent has 48 players but there are only 20 teams per zone which means they only had 40 out of 48 join (they are an overall 196 mil GP guild to our 166 mil GP guild). Assuming the active GP is roughly the same, that's an average of 4.1 mil GP for them to 3.3 mil GP for us. They have 13 players in their guild with a higher GP than anyone in our guild...and presumably these players with the better rosters are not the ones sitting out the TW and so they have a huge edge in terms of DR, Malak, Padme, Han's Falcon, etc. Not only do they have a huge GP edge per player, but they now get a double advantage because there are less teams per zone which favors the guild with less players participating. If the zones required 24 or 25 teams per zone based upon our 49 participating players, they would have to place more teams on D and would need more teams on offense which would somewhat offset their big GP advantage per player.
If guilds can go into TWs leaner like this and drop their weaker rosters to get matched up with weaker guilds, they shouldn't get the advantage of a reduction in the number of battles.
