To be clear, these currently *are* intended to have a shared cooldown with Cannon: Rapid Fire and Cannon: Spread Volley.
These console powers are very potent, especially with the three piece set bonus. During internal testing, we tried it without putting them on the cannon shared cooldown. We found that rotating from Tachyon Burst -> Rapid Fire -> Overload provided an extraordinarily high amount of burst.
We do have an internal QA team, and they're actually the reason why these *are* on a shared cooldown - the burst potential was just too high.
We could have put a long shared cooldown (say, 60 seconds) between Tachyon Burst and Overload, but this would have cut down the incentive to have those two consoles equipped at the same time significantly.
We also could have decreased the power of the individual abilities rather than making them share the cannon cooldown - and I did test it out that way internally - but it wasn't as satisfying.
We're still examining this further, but we would prefer to release a ship console a little "weak" and buff it later than release it in too powerful of a state and have to nerf it at a later time.
Again, we're going to keep testing this internally further, and we'll listen to player feedback. We do read these forums on a regular basis, we just don't always have a chance to reply to every thread (either because we're too busy fixing or implementing things, or because we don't want to make a statement about something that's still in flux and may change).
Thanks for the response and clearing that up!
Where as I can understand chaining these abilities together can give too much burst damage, the linked GCD between BOFF cannon abilities and the console's abilities just seem a little extreme. Currently, it is faster to just not use them, in example, Elite Khitomer Space stf, with probes. Just using one of the console abilities itself won't punch down a group of probes as well as just using the C:SV boff ability. You'd actually be hurting yourself, because suddenly you're auto attacking for the next 15 seconds. At the moment, the only way around this would be to Que up the actual ability itself since its more similiar to a torpedo ability, lasting 30 seconds til used. And Queing it up 15 seconds ahead of time to use it, then switch to cannon BOFF abilities.
Personally, I would think a shared GCD of say 30 - 45 seconds or so between the console abilities, or even higher, would let players keep the rather unique feel of the unique abilities these ships can have, and still not break the game with too high of burst since it would have a longer GCD than the boff cannon abilities would by themselves.
Though, this post now seems like it'd be better in suggesstions. lol
