I missed this edit. I did forget about the penalty for wearing Epic Litany as a good aligned character, but it's relatively small overall. The dps gain against current endgame mobs should be worth it imo.
Full plate is not worth the investment anymore, even more so with the upcoming changes.
With the upcoming balance changes, many things might be thrown into question. I don't want to speculate too much since those changes are still subject to change before going live. But I'm sure I'll have some comments on the pros/cons of str vs dex based and khopesh vs rapier/scimitar after the balance changes go live.
Again, this is dependent upon changes that are not yet written in stone, but I'm considering dropping imp crit ranged. About the only time I intended to use ranged was for manyshot anyway, and the proposed changes will basically kill manyshot for tempests. Melee dps was already so good that switching to manyshot in its current form is questionable, but after the balance changes go live, there's no question it won't be worth it. So if you're looking to fit completionist, imp crit ranged is probably the first feat I'd be looking at dropping (again, dependent on what actually goes live with the balance changes).
