First of all, to clarify the conditions for limits: 14 people total, so 7v7 excluding specs, I'd hope. And limiting 1 soldier and 2 rifles would be per team, therefore 2 soldiers and 4 rifles total.
I think 1 soldier per team wouldn't be great. Imagine someone less skilled (like myself) takes mortar, spends 5 shots just getting aligned, land few, respawn for ammo and repeat. Altogether very little impact on game,while nobody can pick panzer or MG...
Therefore I voted "other" with my suggestion being: under 14 players, allow 2 soldier per team and 2 rifles also (as originally suggested)
Ps I see player Majrik in one of the screenshots... Whoever sees him, pls let him know that "cyber says you smell"... He'll know what I mean 😁
