Since last week's testing, there was a lot of talk on what could be done with the Tempest to make it more useful and not OP in PvP and Alliance. The Current Tempest MKS is too OP based on release reactions.
Suggestions highest to lowest based on discussions. Yellow changes would likely need code changes, due to the Tempest unique properties. Orange are art changes. These would take more time to happen.
1. Change Shatter to Fire. Reduce damage to either 7/7 or 6/8 Explosive/Fire. Add 1 second to reload time.
Popular since it would make it a guided Banshee with reduced angles, very suitable (and fun) as a 'nub gun'. Removes effectiveness against guns and engines (main complaint), improves effectiveness vs armor somewhat, substantially increases effectiveness vs balloon and hull, which is why the reduction in damage. This would also be very useful in Alliance. Maybe more useful than Shatter and fire stacks (at least more rewarding than just burning the AI down with useless shatter damage and OP fire stacks)
ADDITIONAL:
Far too much smoke/explode effect for such a fast firing gun. Reduce or remove explode effect, and add something to reflect the new 'fire' nature of the missiles if option 1 is chosen.
2. Switch Primary and Secondary damage to Shatter/Explosive
This would reduce the effective missile count as far as breaking components without reducing its effectiveness at hull damage or having to reduce the actual missile count.
3. Fewer missiles. 8 if no damage stats are changed. There are currently 13.
Fewer missiles means less damage and graphical effect.
4. Slow down gun movement to make it harder to keep a lock on targets.
Only helps against fast ships. Galleons, Mobs, and Spires would still be cannon fodder.
5. Slow down missile speed.
6. Reduce gun arcs.
Not a popular option.
Reducing ROF was not considered as an option due to players not liking having to sit on the gun while the missiles were in flight. Reducing ROF would have increased this time.
