I personally have not had any T-Posing from me or NPCs. So it is up to you, do you want to use the sprinting power attack perks from Ordinator? Or do you want to freely move as you power attack? However, the unlocked movement can be turned off in the CGO MCM. This allows you to move while power attacking but it breaks the sprinting power attack perks from Ordinator. CGO unlocks your legs from your torso when you power attack.

The main issue is with Ordinator and its 'sprinting furious fighter' perks for one-handed and two-handed weapons. Though it does take some time to get used to in first person. You can drop TK Dodge as CGO comes with its own. I use Wildcat, Mortal Enemies, CGO, Archery Gameplay Overhaul, Ultimate Combat, Sekiro Combat, Nemesis PCEA, Dynamic Animation Replacer, Animated Armory - DAR version, New Weapon Type Animation, 3PCO, Floating Damage, Ordinator, Movement Behavior Overhaul, and Jump Behavior Overhaul. My response to someone else earlier in the week regarding CGO and compatibility. What are peoples set ups of choice when it comes to Combat, melee or magic or otherwise. The downside to not using CGO is having to then use multiple mods to potentially replace the experience, are there any other recommended combat mods that make melee combat interesting? I know I can probably use Archery Gameplay Overhaul for the Bow side of things. What are peoples experiences with this mod, is it worth the headache of shutting out the use of a few others, in particular Mods that use DAR (Dynamic Animation Replacer) and Animated Armory etc. I've seen CGO being touted as excellent, but I've also noticed some issues with the way it tramples over other mods, the compatibility is quite low, it messes up some animations of other mods, doesn't work so well with Mortal Enemies, which is a mod I think I want.

But want to try a melee build, something I've never really done outside of a sneak assassin and spellmace type

I don't usually play melee focused builds usually more mage stuff. Yo, just getting back into Skyrim after years out.
