I completely agree with your point. Interestingly, I feel my time is better rewarded for collecting Triple Triad cards than it is collecting gear and doing battle content. A rare, difficult to get, and useful TT card from 2.x is still just as rare, difficult to get, and useful now as it was then. Meanwhile even gear I collected a patch or two ago have become worthless glamour trophies. A odd few cards are easier to get since 2.x, but for the most part time invested in TT cards has had more lasting benefit for me than time invested in gear.
