Everything looks good, I'm worried commando will be too strong though after that change.

Would also like to see Phoenix max lift range extended by 1 as well.

And would like to see the scaling for odins damage done the same as commandos snipe, Where it gets more damage and health based on hero/marine/elite upgrades.

So the buff that is needed is not for commando, but for Spectre (commando's ultimate hero morph). I'm a little confused about these changes, since we discussed the following in discord:

-buff spec lash (reduce casting time by 1 second)
-buff spec stun vs heroes (increase radius to 1.5, but make it only affect heroes)
-reduce HT feedback range by 1 at all levels, including HTA

We want to incentivize people to morph from a commando to a spectre, but the proposed commando change does the opposite :C

And I'm not sure that reducing HTA feedback range by 0.15 is going to do anything.

Please consider making the changes I proposed above, at least for Spectre. And I would highly advise against the proposed commando change.

I agree with the elite changes.

Im okay if the commando changes only affect its damage vs heros, and then when you go spec its damage works vs elites and heros. I think there is a missing early game counter for heros, and a commando snipe buff vs them would be nice, but in that case specter should also get something to make people want to morph.

Everything else looks good though, maybe slightly more of a nerf to the FB range on HT.

Updated with new changes.

Just want to make sure that if this change is made, should make Ultrasonic Pulse work on heroic units only.

Currently it works on army as well, and we used to have 1.5 radius USP in the past which was OP against armies.

Odin ability sounds cool

I cant stress enough That specter is going to be so OP, I would suggest leaving it alone and just increasing lash damage and just a tad faster lash, like -0.5 time from current lash.

The phoenix grav beam nerf at early levels i dont think is needed. If you leave how it is, and just give it the buff it should be good.

Everything else looks amazing!

Yeah sorry Raiden I should have clarified: meant 1 real-time second, not 1 in-game second (different due to timescale).

So spec lash windup should be 2-(1/2.45) = 1.6 in-game seconds (not 1).

If you have time can you please remove recall from support tower? Its heavily abused.

For the Odin ability, shouldnt it increase attack speed as well?

Updated changes.
Modifications / new content is highlighted with different color.

I would love to see Hk's get some more attack range in the midd levels from like 3-6. Currently the attack range is super bad on them. I think at max level its 6.5 range? And without push they hardly ever attack.

Spec Lash decrease and the stun increase is going to be so OP, you can just stun and then lash and it will die. Really think the lash needs either shorter range or decrease time to lash by only 0.5 instead of 1.

Everything else looks super good and am excited to see the patch!

Also i dont think you could recall savior with MS? Unless its something i didnt know about

Isn't this your account, I assume this was the case.
