Maybe this is a little too niche of an issue to properly be addressed, but being able to quickly toggle a mass of loadouts to enable/disable them based on which tier of PvP you wish to enter would be kinda nice. I'm not one of those people who has loadouts sorted by tier, so I have to go through and manually inspect each one to make sure it's a loadout I want to keep on or off. Not an integral issue either, but yeah simply suggesting it for convenience.
Pretty cut and dry explanation, +1 or -1 accordingly.
This would be more of a workaround for a problem than a solution to a problem. It would be better if you would simply be put in the queue for T2 LD if you're wearing a T2 loadout and if you sign up, you shouldn't be able to switch to a T3 loadout.
