I feel you have to spend way to much time going after enhancement cores, I have 3 guardians as do a lot of other people I'm sure. Now if anybody else out there is like me they have certain weapons or armor that they love and hate to play without, so you end up doing a lot of infusing which in turn means a lot of enhancement cores. I like the fact that there's bounties you can do to get them but I personally think you should just be able to buy them with legendary shards ( for a set amount not double every time ya buy one) or maybe how about making use of them vendors on all the planets, have them sell enhancement cores, or banshee for weapon parts, zavala for vanguard tokens and so on, make use of all this stuff that's in our inventory that's just sitting there.
