Increase power limits of all power levels from 125 to 150or175. By itself give no benefit but by raising the cap and eningeer could easily take advantage of the higher cap with the various E power to and EPS powers.
instead of the orbital spotlight
The engineer instead can instead transport down a bunch of deployables.
basically pick a target
use the power
5 beam turrets are teleported down in a wide circle pattern around the target
3 cover shields spaced around and further behind the turrets also form
and now you've got an awsome flanktastic kill box for your team to maim everyone in the middle.
To me, Nadion Inversion needs to be replaced with Rotate Weapon Frequency. Where its like Direct Energy Modulation but the effects are random where it completely penetrate shields to a normal bleedthrough (only works with beams).
This was used on the Borg in TNG.
And Orbital Strike needs to be replaced with the TOS AoE Phaser Stun.
