I'm noticing what looks like a problem in Hero 5.
Under hero 4, if you changed speeds midturn, your next phase occured when each of your speeds had had one phase.
Thus, if you were speed 5, and were hit with a drain that dropped you to speed 4 on phase 4, you would move next on phase 6, and then continue on speed 4.
Likewise if you were speed 4, and were boosted to speed 5, you would move on phase 6, and then from there you would use speed 5's chart.
Under Hero 5 (and I don't know if this is the same for hero 6.) you only move when you have a phase that meets both your speeds. Now usually this isn't too much of an issue, but taking the above example:
If you are Speed 5, and are drained to speed 4 on phase 4, you don't get to move again till phase 12... dropping you to an effective speed 2 for that phase. (And if you can drain anyone with less than speed 7 to speed one, at any point in a turn, they get no actions that turn...)
does that seem like a problem to anyone else? Is this fixed in 6?
