No point at all? Don't you have to have one of those commendations for each piece you want to buy? So I would have to level my vanguard up 3 times?
twice
if you do the urn quest (you get it after completing the DLC missions) you will be rewarded with gloves. So you need to buy boots and a chest piece from the vendors, and an exotic helmet from xur.
if you have crucible marks saved up, you can level up your crucible rank, or a faction rank. If you have the marks, then you can level up your faction by equipping their item and doing vanguard bounties./patrol/strike playlist. If you don't have the marks, then just play crucible. or just level your vanguard up twice.
If you have multiple characters, they each have their own vanguard level, so if the other character is close to leveling up, you can get the commendation and buy the armor with it, or put the commendation in the vault.
EDIT: forgot that you don't need them for gloves and boots. I would just buy boots (not gloves, see reason above), and level up once to get the chest piece. then get helmet from xur
