The additional item surely makes a difference in a fight but it will be more difficult to use and less effective. For example the cooldown, warmup is longer than usual. In addition the time the item is active can be shorter/longer etc. We are currently in the testing phase to balance each item type accordigly so that the extra item slot will not be OP.
i feel like this downplays the impact an entire additional item would have, this isnt the same as like Asura cortex for example where you have conditions to using it, its just an additional button you can press for no cost except energy i guess
Currently cqs especially otbs tend be very unbalanced due to differences in skill of players but tech absolutely plays a role too, now we are just widening the spectrum of imbalance even more...
Balancing items based of cooldown warmup and duration is inherently flawed, certain items are much better off balanced by strength such as bomb and os i mean i certainly dont think its funny if in the future u can have it be a theoretical possibiliy that everyone has a functional full damage os or bomb and u can do funny instant wipe strategies with any ship, or do funny spam strategies with any item even rfs turrets domes or anything of that nature especially since if i understand it correctly it will only cost cryonite to swap items on the 9th slot and maybe remnant bp parts for tc
Balancing items like these by adjusting cooldown or warmup is almost certainly going to be more challenging to getting them into a healthy state than by simply nerfing their strength accordingly to account for the fact that they can spammed as many times as there are players in your team, again there is 0 disadvantage to using item 9 only opportunity cost
