It's too large of an investment that inevitably cripples your AEQ.
To be more precise, it takes a LOT of BT's to enhance a multi train skill slot up to 5. If you do all 3 slots... times 5 enhancements... by the time you gather enough BT's to enhance all 3 skill slots up to 5 you'll be pretty deep into your build (guessing end of second season or start of third). You'll have no BT's saved at that time and most other people will be shopping for their 1st AEQ piece (unless they plan to build them all).
Bane (post above this) is pretty close to what 75% of the peeps do here. I go 30% myself and have no issues with AEQ. (But I don't put anything in the free slot). And positions that have a limited skill set (Punters, kickers, and even some QB's [depends on the build]) can go higher for 2 reasons. #1 is they can get by with less AEQ (like only 3 pieces) and that's because, #2, finding 4 good AEQ pieces is hard for those particular positions (when rolling for the AEQ).
