its not necessarily firepower being the issue, but for a ship with that much firepower at that PL it is a bit too tough for my liking. The problem with the 10 sag ea tourney fleet is that by the time you inflict enough damage to seriously deplete its firepower youve probably taken something like 100 odd missile shots at you. Not many fleets can take that kind of punishment (even Vorlons). Ironically the best suited fleet to take ON that sort of force might well be another EA fleet (with the abundance of interceptors).
As a fleet to take on the 10 Sags though, aside from Earth Force, how about a primus and 3 Sullusts? Serious beam firepower with decent defensive capabilities too.
Or how about a good old fashioned Sharlin to the face tactic? The majority of those sags will fail their stealth and 6 Neutron lasers should take one or two out quite quickly...
The problem is that whilst I can come up with ideas on how to fight the 10 sag idea, Its still seems a bit tough. Id say move em back to raid, maybe a TINY boost though. (It seems to me that at the moment youd be nuts to take an apollo over 4 sags and the apollo is supposed to be essentially a better sag basically and whist it IS better, its not better ENOUGH

for 2 pls difference)
