At this stage, it's been updated so little and most of us have so many tokens that any item they add to there is practically given to us instantly. We just grab it at the vendor and forget about it. It's a rather poorly designed system.

What might have been a nice idea, if they wanted to make achievements relevant, is to add new items to the vendor for achievement milestones. For example, you'd unlock something at 1k points, 2k, 3k, 5k, 10k or whatever. The higher milestones would give a few rare items to chase for, a long term goal or two and encourage dipping into different content. Could be fun.
