There are 4-5 hero tribs daily and 5-6 tribs are levelin up quickly, which makes outies to suck big deal.
There are some nexans even with quest form, but they never fight fort or tribs now. Though they gladely would raid scions, empire or tree together with forties/tribs. But mostly, they are bust with villagers and do not care for anything else now.
In Empire, there are only two heroes, others are lowlevels but some of them have potential (2 or 3). Bbut even should they hero, it will be something like 4 vs 20 (if we take fort). Hopefuly, election of the nex emperor wll change things, though if it won't be Eleagra, Empire will suck big deal again for loooong time.
Scions - looks like they are totally demoralized by forties numbers and only Rindros and Zynzyn are playing now on hero ranks. They are good, but they cannot stand all that horde of overrewarded, overboosted goodies (some which, I suspect, are being played by top imms, and thats where their surepowers comes from).
