If you aren’t having fun in endgame playing Paladin, try something else.
First and foremost I would like to say that I have been having a blast playing paladin this season and I am by no means saying Paladin is not fun to play. But with the current state of Paladin in endgame (underwhelming) it is likely better to switch to a new class rather than waste time struggling through t12 bossing and high level pit.
I have played most of this season as a hammerdin and have nearly completed the build to perfection. Currently Paragon 215. I have all 3 required mythics. Near perfect aspects and uniques. Optimized charms. And 75+ level on all my glyphs.
I shred t12 mobs and base content but the true endgame (pit pushing, bossing, and uber bossing) is an extreme struggle. The damage scaling on most paladin builds is just not there. Clash seems to show promise, but is much slower for everything else.
Instead of making minor changes and adjustments, I decided to roll an alt barbarian.
I used t12 whisper caches to go from level 1-70 in about 60 seconds. Then used some gear and uniques I had in the storage to gear my barb. Within one hour I was at t8 and now after getting some class uniques and aspects for a few hours. I am doing content easily in t10.
Obviously my paragon and resources are making a huge difference in the leveling process, but other class gear is just simply more optimized for damage. I fully plan on making my barb a boss killer and never bossing on my paladin again.
Making my barb I have had significantly more fun in 4-5 hours than I have had the past week on my Paladin. I still love my paladin and will use it for quick farming, but the goal of playing diablo is to have fun and for me that means dropping Paladin for endgame content.
