Did anybody even playtest this combat style? It seems a bit on the weak side and even worse, lacks an obvious identity, is just "the one that can use a third action to suppress at long range and maybe can tank". I suggest adding the following action to it as well:
ERUDITE ANALYSIS [free-action]
Trigger: an enemy you have suppressed targets anybody except you with a Strike or other offensive action
Frequency: Once per turn
When not defending against attack, you can analyze enemy reactions to suppression, drawing useful conclusions about their capabilities. Make a recall knowledge test regarding the target. You may end the suppression to roll class DC as a general skill on this test (e.g. in place of Religion but not Undead Lore against undead).
