Please help me understand this error:

In normal arenas/bridges/duels - we tend to have replicants in a interesting manner.

1) The lowest level gets replicated with dragon summoned as in AoH or 7b
2) Replicants of fixed level come over as in DoT

So, why the hell does Sea Battle have replicants with highest levels?

Its quite frustrating when people take advantage of this damn thing!

For today, my rant is ->
Vaalor acted as cowards by not doing sea battles until Betepah got online.
The other side -> Even the lowest level players are able to make the best out of it, because they ensure that only 5 or 6 players join on their side, thereby giving the additional 3 or 4 high leveled replicants.

So, how come this is balanced???
