I get what the OP is trying to say, but I don't understand why they are deciding to stay in a smaller guild. Raids run less frequently, TB is also a huge disadvantage. With negotiator, malevolence behind get2 and GAS, malak, Hermit Yoda, Wampa behind get1 as well as wat, rolo, probe droid, kit mundi earned within TB events. To be arguing for ways to even it out for raids is irrelevant. TB cannot be levelled out. Get in a guild of 50 members. If your guild of 25 is a great, close knit group then you would br able to maintain that with a merger.
This isn't an individual game, you need a guild that matches your level and goals. I guess if unlocking toons like WAT in 2 years as opposed to one, then stay in your smaller guild.
