It seems to me based in the discussions around shifters of late:
- Currently there is the regen form debate
- Then there was the whole dolphin debate a couple weeks back

That there are forms people really consider as a must roll/spin without trying them at all.

I actually think this is a reasonable suggestion and would go as far to suggest the following tweaks to it:
- You cannot roll/spin until confident in the form
- When you are confident you get a timer either in the forms list or the character affects which gives a small time frame in which to roll/spin once the timer expires you are "stuck" with the form.

I actually think this would help diversify the playing field somewhat and perhaps some forms that never really see the light of day may start coming back out again.
