On leveling new alts I stopped spending planetary comms. Pre 2.0 it was simple - get rid of them, buy gear on your current planet, or they will be wasted. Right now, there is no point to get rid of them, as you need those 100 capped for Blue 58 mods from Makeb vendor, which substituted free Tionese gear.
I'm though lucky, as I've cybertech crafting alt, that allows me to swap blue mods every 4 levels, so I don't have to bother with planetary gear. But, if I had to upgrade the traditional way, it would be the choice of either upgrade gear, or saving it for 50 mods. Thus I'm not sure if the 2.0 change was beneficial after all - before it I definitely bought more stuff
