The clip size of 18 for the TAC AR is too little.

The argument that 18 is fair because it is the same number of shots a ScR can make without overheating is a poor one. Properly managed heat buildup on the ScR can circumvent that restriction allowing the full 36 shots before reloading.

By limiting TAC AR to a clip size of 18 a virtual overheat mechanic is hard coded in and is inescapable.

There is also the ability of the ScR to charge shots for high alpha damage and, properly managed, can be done multiple times within that 36 rounds and even within 18 rounds. The TAC AR does not share this ability, making those 18 rounds even less effective by comparison.

And then there is the issue of range. ScR is a long range weapon. If overheat were to happen, chances are user is far enough away from opponent to allow for cool-down without user being killed in the interim. This may not be possible 100% of the time, but the possibility still exists and the probability is high.

Not true for the TAC AR. It is a cqc weapon. Keeping opponents within optimal range can be a dangerous game. Stopping a firefight in cqc to reload after only 18 shots, often one or two shots away from beating the opponent, leaves the user highly vulnerable to continued attack and often results in getting killed. This mechanic is completely counter intuitive to what cqc demands of a weapon.

I propose increasing the clip size to no less than 24 rounds.

I certainly cannot fire 36 shots consecutively in rapid succession from my Amarr Assault and when I try to do this I suffer at least a 5 second seize duration and then a cool down duration. Basically a longer than usual enforced reload.

Tac AR to fire 21-24 rounds at best since it does not suffer over heat at all.

No, the TAR is fine, I use it all the time. It's like the scrambler rifle but more accurate, giving it a bigger clip will make it OP.

The scrambler rifle doesn't get up to a 50% recoil reduction, so getting more shots to shoot than the TAR seems balanced to me.
