Could be that. Heh, also likely some teams might need some help vs. the AI and the merc sees the need and responds like any savvy business. The most useful military services will likely be:
Attack any Team for x number of turns options, which has Atlantis attacking any of the available provinces of a client's enemy (AI or human) within reach. If I were the merc I'd lower the prices on these, maybe offer a 1 turn contract option.
The targeted attack services on a specific province are much more risky and difficult for the merc, so I'd probably raise the price on those.
You can already give the merc the province taken in such attacks by simply not claiming it, but if Zegc wants to offer an option that lets him retain the provinces for a greatly reduced cost, temporarily or permanently, that's up to him. Maybe excess Atlantean provinces can be rented out or something for certain amount a year!
