Only accounting the new brok-- err shiney stuff coming with Season 8.
Medical Vanguard - not addressed, bugged with Nanite Health Monitor and Elite Fleet armors (runs indefinitely)
Nukara Reputation Cold Weapons - they probably need the same treatment it has been given to the Cryo Pulsewave against players
Melee more efficient against crouched characters - change made for NO REASON; Superbuffed Lunge is already powerful enough to one-hit kill most setups other than Omega
Tholian Stasis Drones - Willpower should resist this (1~2s tops with full spec), place an immunity afterwards, and the target should be EITHER immune to damage while held OR broken out of hold upon taking damage
The list is probably much longer. Sad to see ground mechanics getting so little attention overall. (Aka lolground.)
Crouching is a defense versus ranged attacks. It makes sense you'd get slammed harder via melee attacks since you can't defend properly in a crouched position.
Sure you can. Part of the entry-level college course I took in Aikido included defending and moving from a crouch. It's awkward, but you are below the center of gravity for most opponents and really only have to defend from one direction: up. Don't get me wrong, it is not fun and really limits your movement, but you can defend from a crouch against a standing attacker.
Yes, I said entry-level. That means that a combat trained Starfleet Officer or KDF Warrior should be just fine, if not particularly mobile. Now a Romulan farmer... probably more vulnerable.
