I'm also on the side that thinks this isn't really a problem Anet "needs" to fix. You know who the blob group are, since you apparently keep losing to them. You can either choose to join one, or keep doing what your doing. The choice is yours.
Just a side note, if you decide to take your, say, 24 and form 3 8-man teams all talking to each other and looking out for the enemy zerg, you should have no problem taking more points than them. Avoid fights and play PPT. Eventually the larger teams will have to divide up their zerg to match or watch themselves control almost nothing on the map. I know a lot of people don't want to play that way, but it's the only way you're going to "beat" the larger groups unless you're willing and able to match their numbers.
Lastly, I do think there's a design flaw when just about every party needs a Firebrand. Either stability should be fixed, or more specializations should have the ability to match what FB's can do in that area IMO.
