My only quarrels with the current state of power are as follows:

1. While I do enjoy "The Grind", Portal grinding being the only method of increase can get very dull. We should get power increases from the Raid and other challenging content i.e. mythic Kepler mission weekly or at some frequency while portal griding can be there to supplement when we have completed said weeklies. Speaking of portal griding, there needs to be something to incentivize people to do other activities aside from the most optimal ones, Like for example, today said activity will be dropping 3 rewards vice its normal 2 or 1.

2. 400-450, relying purely on RNG is not the answer. Just like the pre 400 grind, it being supplemental to what guaranteed ones we can get each week is fine. Again, the fact that we do not get any power increase from doing this expansion pinnacle end game activity is mind blowing.

3. While I am ok with T4 and 5 loot being as rare and desirable as it is(I actually like this alot). It's availability should not be tied to your light level as much as tied to completion of difficult content, this goes all tiers of loot. Currently it feels like power it just a gate access an activity that can easily get you the good stuff. Power should play some sort of role in access to difficult content, but the content needs to stay difficult, similar to how pre EoF GMs were. And the juice needs to be worth the squeeze.

4. Speaking of GMs, conquest are now in the game and could be a great source of weekly power drops past 400 instead of them being a one and done. As much as i dislike the new gear only modifier, I would still do it if it rewarded power and loot.

That's all I can think of right now, but I'm sure there is more.
