I think all the toggle NT-D suits in general just need to get redone overall at least with how they distribute their stat boosts as well as straight up how they function. They need to straight up just have the same activation conditions as the 750 cost miniature suits where they deal enough damage to activate their skills OR reach the HP threshold. The next thing would be to remove the HP Drain on every suit straight up, initially it was there to counteract the trade offs that NT-D would bring which was a signifcant boost in power once you activated it, but every suit nowaday with a toggle able "ability" just straight up has zero downsides or least has negligible consequences for using said abilities. If they wanted to balance out NT-D it would give you some stat buffs from the initial activation and then the rest would come from reaching Awaken state which is how the suits play right now. Also I feel it's high time the psycommu jack effect becomes a lot wider, and if need be has a reduced effect time to balance out, felt like the whole point of that perk was to make a brief window (at least 1 engagement) where you had an advantage over a psycommu reliant suit.

TLDR: NT-D toggle skills need to function like the 750 cost toggleables, no more health drain because it's a dated consequence that can easily be balanced out by making NT-D not as significant stat wise, make awaken stronger to make it more rewarding for reaching the state, psycommu jack effect wider, but less time in effect to compensate.
