I like how it is now, it makes creating good build challenging and you always have to make compromises
Compromises? Those exist only in pvp build making. Otherwise it's like this for example:alt1: repair 300 + sg2alt2: lockpick 300 + bg2alt3: science 300 + doc2alt4: OD200, taxi + armorer2Compromises and tradeoffs are out of the question when we're talking about support abilities.
There are people who don't play the easy way.
Or just give character with trait loner possibility to learn 5 not 4 proffesion level.
It was reduced to 3 in this Wipe.I would make Add Profession Level a Level Perk with 2 ranks, the second rank being available only to Loners.(And let Loners buy the Tag Perk at Lv 9, and make it available to others at Lv 21.)
