Yes I understood that part. As Twisted mentioned, there were versions of the IH toggle some of which could have been over or under powered based on opinion.
I would be happy with an improvement or two to individual Regeneration power values...
But frankly, don't want open pandora's box to the current 'dev/player in-crowd which is deciding changes'. Some of whom have already shown some level of not understanding the set, a desire to drastically overhaul it, and/or tunnel vision for tuning things with preference to 'end game' (which doesn't exist), min/max level builds, and pylon times while ignoring the other 90% of the game.
If you want your toggle suggestion to be considered (not by me but by those who count) , it would need to be more specific.
