since most people don`t care about playing as a team in public matches, you find yourself dying pretty quickly as a frigate at the front line.
you are slow as hell and if you move to the front and stay at a node for example, your whole team will fly off to the next node and you be sitting alone there, dying to the next enemy ship that circles you, faster than you can track him.
following your team mates to the next node doesn`t work very well either, since you are so slow.
i tried the interceptors as well and i had some good and some aweful games with them. maybe the most drawback is, that your rep costs in an interceptor are as high as in a frigate, while in an interceptor at the front lines you die a lot more often than as a sniper in the back.
with the current prices for new ships and modules you can`t keep buying at least 2 lines in the tech tree and equiping them, even with premium especially if you die more than 1 or 2 times a match…
so if you want to buy some ships and modules as you level up, the most viable way to do this is sitting in a sniper frigate and since people try to play a game the most “efficient” way, go figure.
getting in and out of the sniper mode a lot is possible, but not very effective in a battle, since you have to wait rather long for the desintegrator to be charged, what is effectively a lot of wasted time in the heat of battle, while your target may be behind cover until it finishes.
if the frigates should play a real “tank”, it should have a different special ability, that supports this role.
the frigates as they are now, can tank a lot, if equipped correctly, but they can also die VERY quickly against well equipped inties or fighters. in the heat of battle they are out of place right now, since they can`t track close range enemies good enough when they are moving fast. all of their stats (except their high armor and shield values) shout into your face: “keep your distance from fights”.
