Agree the huntung gear is more expencive then the Explo BP, but
hunting vanguards or dasp or any other expencive mob, could drop some nice uL items that can cover all or at least big part of your investment in gear.
And you got the option to loot ESIs, that have a nice markup, too
crafting explo you can´t loot any decent BP as it is components, which have very low markups compared to other BPs like attachments, best you actually can loot is Explo IV BP
I can´t see any difference, if hunter owning uL gear only, can repair all for TT and buy ammo for TT only it is exactly the same thing than crafter clicking Explo BP for TT only.
The difference I actually see, hunters can find markups, while crafter clicking explo can´t.
Another difference is the speed, even with best gear available you can´t kill a Dasp every second, but you can do that turnover with Explo IV, so there is a little advantage for the crafter to see more globals in the same time (doesn´t mean it makes them profit)
And hunters have some other options to make their hunts more efficent - pre damagers, hire faper for decay still only TT input, what a crafter can´t do with the Explo BP.
About the skill requirements: Hunters skill damn much faster than crafters!
