Well, based on everything I'm reading here, and knowing my original question was a close call, if I had to do it again, I'd take the shot.
At the time I didn't know if anyone might be just outside icon range or upping from the enemy base, and I wouldn't want to end up even slower and lower than I already was. I had a good shot, took it, and glad I did, although i understand some might consider it cheap. It was close, but I'd rather gather up alt and speed, which takes time, for the next fight than to keep this one going any longer since we already dropped our speed and alt so much.

The key point being it will take some time to rebuild E after a slow turnfight, so the quicker one can get started the better.
Thanks for taking a look at it. Much appreciate the feedback.

DMGOD for a fun fight which did last several turns.
