You must have forgotten about running around in circles on the map just to collect enough spin metal to unlock ONE perk bubble on your armor. That wasn't fun. TTK has done more good than bad for Destiny. Yes, I do miss the old strikes being on the heroic difficulty playlist but that doesn't mean they are irrelevant. You can go to the legacy strike list and play them. Between encoded engrams dropping like candy and three of coins, you can do the old strikes and still get decent loot. Same goes for the old raids in regards to the three of coins.
