I dont know if this have been requested or not.
But if not please add additional tactic slot from the current one (3) to at least (5)? Because with positional play coming in (even though we dont know yet how it will be/how it will impact the FM tactics) but that should made more tactical variations. So instead of 3 slots for quick tactic/train tactic probably can increase to 5 of course with the downside is being reduce in effectiveness probably? But we see how many tactics nowadays team played (Brighton/City/Arsenal/etc) against different oppositions.
