I'l just copy what I wrote in the beta section (well, about 50% of it):
[...]
To be clear: Formica rufa soldiers are very likely to be the ONLY ranged unit in the game worth mentioning (at least until termites get introduced).
There are a few other ants that also spray formic acid (like Camponotus ants) but none of them can do it at such a long range.
Most ants will be close combat or at least very short-ranged.
How do you plan on introducing Trap Jaws, Leafcutters and all the other cool ant species when essentially all you need in the game is a few tanky ants (Atta soldiers or Camponotus majors) to stall the enemy so the dozens of shooters behind them can wipe the floor with anything that gets bound by these tanks?
I've already seen how overpowered combinations of tanks and DPS creatures can be (go to 2.1 on medium/hard and attack a large hermit crab right before the morning dawn, you can easily loose multiple dozens of ants to a tiger beetle that just chops through them while they keep poking against the shell of the hermit crab) - this will be utterly gamebreaking.
F. rufa shooters should be support units, not main damage dealers.
- In the formicarium mode they can gain an ability that places a debuff on targets increasing the physical damage these take. THIS IS PERFECT. Reduce the poison damage and give them this ability for free.
- Some units can apply debuffs that confuse or stun the target. This might work as well - make enemies that get hit by rufa shots get stunned for 1 second with a cooldown of 5 seconds before the debuff can be applied again (this is for mortars, rapid fire ants could get a debuff that decreases the enemy's attack strength instead).
These simple changes will make the shooters a very viable support unit that can increase the soldier's effective damage and reduce the losses frontline units take. Their damage will be rather low so they won't nuke everything off the map (even if the mortars keep their AOE and can apply debuffs on multiple enemies this will not lead to hordes of enemies instantly getting bombed to zero HP).
The shooters new role will also lead to a different metagame - no more massive hordes of shooters but mostly soldiers with a few supporting shooters between them (because the debuffs do not stack so hordes of shooters are completely ineffective) - basically the gameplay we played and loved in the demo levels, the stuff people are actually expecting from the game.
