Save your AD for a ioun stone, like the Stone of Allure (cheapest). It is one of the best investment as a companion, which gives you 100% stats of anything equiped by the ioun stone.
The possibility of the universe collapsing into a singularity is higher than the birth of a perfect MMORPG.

Not sure where you're getting a lot of AD from, but by level 60 what you have will not be that much.
Best things to spend AD on are:
- 110% mount (if you don't want to buy a mount with real money)
- enchantments, especially weapon and armor enchantments
These things all costs 100s of thousands of AD so don't worry about it too much now.
You really don't need to spend anything while leveling up.
That 70k can go towards a respec at 60 after you get a feel for your toon with all the powers available.
Maybe buy some blues as you go but don't spend thousands for a few hours of use.
