Hello!, I am not one of the normal beta testers, but I felt I should reply to this topic specific. First, I thank the devs for all the work and time they spend on a game where they get paid nothing.
As for the topic, I think the stated implementation will be bad, even in the said best case scenario where you drop four toggles or even six toggles. The reason is that toggles are not all created equal. There are toggles that add damage, there are toggles that add special effects, and there are toggles that are used for survivability. On the AT's I play when a survival toggle goes off I want it back on as soon as possible, A damage toggle can wait, or I may not even turn it back on for a while.
I do like the idea of toggles coming back on automatically though and I have a suggestion, although I do not know if it is possible.
Instead of turning back on all the toggles at the same time, give the toggles a priority number and turn them on based on the priority number.
For instance defense and resist toggles might be assigned priority 1, and damage toggles might be assigned priority 3, you would turn the toggles in priority 1 back on 1 at a time every 3 seconds or so, and when those toggles are on you would start turning on toggles in priority 2 and so on and so on. This would let the important toggles start to turn on early, while also meeting the devs desire to not overpower turning on toggles. It would also make it more fair to AT's that only use one or two toggles.
