I'd like them to fix already existing power armors before starting to make new ones.

My impression is that Power Armor is supposed to make a man (or a woman) a walking tank, that you can shoot with small arms and not make a dent (actually this happened in the game with a mod that removes the 20% damage bleed trough, 250 5mm round to a APA, no effect whatsoever). I used that armor in the final quest and CL did practically no damage to me. The chinese Hei Gui armor (aka Chinese Stealth Suit) is for those who prefer mobility and and speed over lasting power. US army didn't seem to have an equivalent. I doubt Recon Armor counts, as it is actually just a suit worn under a Power Armor, in GECK it's referred to as "Under Armor".

Yes it's the way DT is handled in game that makes PA ineffective.

You can dodge fire but it requires work and is not always that effective.
Combined however with perks and strong weapons, it makes it better than slow heavy armour for avoiding damage.
That just defeats the armour types imo, slow and at least 20% damage from every automatic weapons bullet in PA..
Or run, cover and shoot first with leather and still avoid most NPC's damage, not really a choice ( apart from a role one. )

As to its stats, if a fast mobile suit go with what you had OP.

i want a deathclaw slayer power armor based on the tribal power armor, but with a deathclas head on the shoulder and such

My http://www.newvegasnexus.com/downloads/file.php?id=37983 mod has something similar - http://www.newvegasnexus.com/downloads/images/37983-1-1290879310.jpg

Stats:

Weight: 29
DT: 19
Health: 625
+15% run speed

I like those ideas.

Maybe it's not a pre-war military prototype, maybe it's made from parts of T-51b, T-45d and things like scrap metal, scrap electronics and a good tinkering mind by some Brotherhood scribe? Then it'd be a Brotherhood prototype and not a prewar military prototype. Or it's some wasteland mechanic who is a wonder child with machines and the likes, and maybe he got ahold of two pieces of these suits (dunno how, story would reveal) and a lot of other parts, and he made this prototype, which you can help him with in a quest. He also get help from local teenagers/young advlts that idolize him and want to help him in anyway, but they've not wanted to help for a time now since one of their friends died trying it out and it flipped out, broke some bones or gave him a shock and there's no doctor, or no skilled doctor, anywhere close.
