Then so be it that SCIR0N should also attack TSE that are coming up on HOPLOS and will eventually get to HOPLOX and do the same there. From what I hear, it won't be long before they intend to do that anyways. But it's alright, I understand your point but at the same time, you're defending against an ally...us.
Even though they're Ex-SCIR0N, they still chose to leave for another tribe, they should not be asking SCIR0N to tip the scales in their favor. I know me personally, just the way I see things, if somebody in HOPLOS was being supported by a SCIR0N player, I personally would talk to the SCIR0N player, ask them to remove support, if they did not, I'd refer to the council of SCIR0N about that player, if nothing was done, it's liable that I attack that SCIR0N player if he's near as well.
It only seems right, you kill an allies troops, he comes after yours.
