I think taking away base ability to do splash damage from banshees is not the way making them unique. Maybe unique useless, if you want such kind of uniqueness. Compound don’t need 5% chance of volatiles, you just making tanks less useful. So your point about stukov as i see it: “Let’s make “unique” units for stukov, but everyone just go on play infantry because mech is too expensive and unique in their inferiority to infantry”.
Artanis lacks dps. Dewarp is elegant way to fix it: You pick temporal buff mastery, warp in units, enjoy the dps. Then you consume charges on building (which btw will require more resources for buildings, to provide enough charges for dewarp, and refund cost may be dependant on unit’s current hit points for the sake of keeping healing support from ally relevant) to dewarp them, and get ability to warp them again with newly applied buff. Ofc with this change some numbers on both masteries may need tweaking but this don’t change the point. Other way is just to give artanis units flat dps increase or cost decrease, but this won’t be as interesting as dewarp mechanic which also helps with mobility.
Something around 10-20% discount on phoenix i guess is just the thing that needs to be tested. But knowing how do you like making OP thing I’d advice just give them 10%.
Viking transformation speed is not enough. I bet you never tried to play using them actively.
Just Die enemies does not receive second life. In that case Nova’s snipeshot energy regen would trigger for killing off first life of unit, but that’s not happening. It’s a bug that should be fixed.
Auto-cast for blink ability for stalkers is the thing that should have been for every stalker in the game from the very beginning. Other units just attack automatically and have no problems. Blink is the essential part of this unit the same as attack, it shouldn’t be special ability for some of the stalkers. If auto-blink makes the relevantly stronger, np - just increase their build cost a bit, it’s not a big deal.
Instigators should have something more interesting then auto-blink. For example, give them energy and bind some ability to it. My thoughts about it: Give them ability to do bounce attack (3 targets, some minor cooldown like 5 seconds) which costs energy, and make their blink cost energy too. So they would benefit from energy regen upgrade, and allies that regen energy, and Instigators may want to not turn auto-cast on for saving more energy for their bounce attacks(which can be turned off too ofc). Other idea is to give them some overload mode, that increases their dmg by some decent amount (50-100%) but each shot deals dmg to Instigator too and drain energy. Also they may lose their anti-air bonus dmg when attack air, so it won’t make karax good AA commander in an instance (which would be way too dramatic change).
