Well, PA is very sixy itself IMHO (damned, I just love it - I'd love it more if they kept it like it always was (an armor, not a damned mech -.-), while really making it what it's supposed to be: Something that enhances a soldier far beyond what's normally possible (strength, movement speed (come on: it shouldn't slow you down it's got servos exactly for that purpose!), durability (small arms shouldn't damage you at all - the enemy should need heavier weapons to even scratch you!) etc. etc.)
Well, I hope that it becomes less of a pain the more you upgrade it (if not: Mods -.- I hate having this cool armor and not being able to use it) - it would fit the lore (early models needed to be recharged all the time, but later models (and early ones that had been upgraded) didn't because they had been fitted with a power cell that lasts basically forever (well: a century of continued use as far as I remember!))
greetings LAX
ps: Who said we can't fast-travel when wearing it and: Has that been confirmed?
