I understand that a lot of the Mythic raiders hate the TF system.
I'm on the opposite end of the end of the spectrum. I love the TF system as a casual player and I hope it is always in the game in some form.
The fact that I have a chance as a casual player to get something really really good. (yes even better than Mythic drops)is just awesome and has a real impact on retaining me as a player everyday.
there should always be a chance that you will get something really really awesome and powerful in game even though you dont have the interest or time in working in a very structured group and commitment to get it that lvl of gear normaly. No I'm not saying i should be able to get a full set of 955 gear as a casual player but that I should have a chance at 1 or even 2 piece of that lvl gear just from doing normal and heroic content.
The TF system is really great and keeps me playing knowing that if luck is on my side one day I may get something really awesome.
