Question about transmutation
No, transmutation is only on the specific item. There are enough ways to get free charges that it’s not really a big deal though.
Sometimes you also have people who use different skins for particular weapons or armor – I know I like having a different appearance for each armor set on a single character.
I generally just skin exotic armor or weapons that I’ll be using for a while though, so I don’t spend tons of charges up to that point. I would have suggested using outfits if you hadn’t specifically mentioned weapons though.
I’d also highly recommend you stick with ‘ugly’ weapons until you reach level 80 and buy Exotics you will stick with for a while. Unless you map/PvP a lot (or never change your look) you’ll never really be swimming in charges. I had 100+ at some point (a lot of PvP) and now I’m always low again. ^^"
It’d be far from a perfect world if all same-type weapons would automatically be the same skin; I use multiple weapons for different situations (10% more damage at night or 10% more damage vs certain foes for example) I’d hate not having the choice to give them different skins, not only for cosmetic purposes but also convenience. (No way I can quickly prestack 25 might with ~3 Scepters and ~6 Staves all with the Lovestruck icon and still get on the right Slaying/Nighttime sigil after. :p) Could be me, so many times I realised I was on my Strenght set instead of Scholar or vice versa whilst using an outfit. ;-; None of this likely made a lot of sense yet, but in short, the freedom to give different weapons different skins is highly appreciated by me.
I wouldn’t like the gear to remember the look across all of them. It couldn’t be kept to a particular char as a lot of the gear is account bound when used. All my ascended weapons are account bound and each char has it’s own look. My Mesmer has a different greatsword skin than my warrior or my ranger or my guardian for example.
ANet may give it to you.
