I'm enjoying reading all of the suggestions on how to balance HotS and make it fun again. I read in a post that David Kim is interested in reworking the Raven and Void Ray link here I thought that perhaps we can have an actual discussion on how to rework the raven.
Before we begin, rework to me sounds a lot more aggressive than tweak. This means that in HotS, we could possibly have a completely different unit. However, it will likely remain a caster built from the starport.
Allow me to pose a few of my ideas. My ideas are tweaks, but I think they would help
1) Auto turret at the moment is a fairly blah ability. However, I found that it is particularly good at killing widow mines, since it cannot target the turret. However, if you drop a turret adjacent to the mine, your raven dies. As a result, I think increasing the deployment range of the auto turret would be helpful. In addition, I would like it to be able to be dropped on lowered supply depots, creep tumors and units, just like a forcefield. Also, I think it would be cool if the auto turret had detection for as far as it can see so it can effectively deal with burrowed units without the raven being there.
2) Seeker Missile needs either to be replaced or reduced in cost. 125 energy is just too much. For 125 energy, I want a freaking missile that shoots at 9 range that deals 100 AoE damage like a tank shot. OR maybe a shot that does 160 damage to one target and 40 splash....sounds familiar....Currently, having a missile that does about the damage of two tank shots on air and ground units for 125 energy is really not acceptable.
3) A popular one on this forum is to replace HSM with Irradiate....
4) My final thought is to reduce the amount of upgrades needed. Make corvid reactor one upgrade and one other upgrade that combines range, armor, and duration into one. Building armor and hi-sec auto targeting should remain, but they should not affect the raven (or alternatively, they should further enhance the ravens abilities.)
