i think the bounty system should be changed all together, some alliances out there ( i would guess the powergroup of 5 alliances) are simply also bashing smaller alliances to zero EVERY PLAYERS of these alliances just so they can collect bounties, so the situation is that you get some top 5 alliances bashing in waves of 5 or 6 players on smaller alliances so they can collect the kills and bounty from smaller players.
If i might suggest an alternative, make it so bounty is dynamic (seriously reduced once you attack under 90% of own score or something) so these higher players won't bash only for bounty at a range of 30% their scores
