I've noticed while playing lockdown that amongst tier 3 players a huge variance in player potential arises because of trinkets. Many players have 2 damage or attack speed trinkets and I've even seen some with 2 +5 heart pendants equipped. The addition of two trinkets like this makes a HUGE impact on gameplay. A player equipped with two trinkets is generally able to do a lot better than somebody else with all 5* equips but no trinkets, let alone if there are any players in game that are 4* (then they are just running in god mode).
I think a "higher" tier should be introduced for those with trinkets equipped in addition to their other gear. This can be some sort of T3+ or a "fully loaded" tier or something.
Note: I generalize this to T3 because in lower tiers trinkets aren't (or at least shouldn't) be a main priority.
Thoughts? Experiences?
