It's a non-issue when running EE. It's an annoyance when running EH because you have to run many extra quests or use a very restrictive playing pattern.
For EN players it's a showstopper. Whatever # of quests they run to get to 28,, they will need to run 3x that many to get enough COVs to ETR. Considering most EN players run slower and play less to begin with, this amounts to months of extra work. You must pay for a heart if you run EN or grind grind grind grind. The casual player penalty to ETR is over 100 quests. That's how it is - no free rides you either up your game, grind, pay or work on new alts until you have enough seeds.
I think getting 20 epic tokens was an easier task, but I don't think the new system is bad. It's designed so that Turbine can make money if you run on lower difficulties. That's fine.
The system works great for me, but not for everyone.
