Heh... BiS is Best in Slot, or in layman's terms the most effective piece of kit you can get in that slot for your build. Bumping Glyphs is my term for leveling paragon glyphs but you wouldn't see that until after lvl 60.
One of the features of D4 Seasons is that paragon levels carry over to all characters so once you've gotten to a certain point with your first character (in my case it was paragon 286 from my WW barb) you automatically get those paragon levels for any new character once you unlock paragon levels by reaching lvl 60. That's a huge boost to your newly rolled character that kicks in when you reach level 60.
One of the biggest things to watch for in the higher levels of the game is the difference between damage multipliers vice additive damage. A stat that does 50%
(x) is a hell of a lot better than 50%

After another full day at this paladin and getting some better gear (4GA BiS amulets don't hurt....

) I'm at the point where T4 Ubers are under 10 seconds, and that's with my glyphs under lvl 70. Definitely overpowered, and really highlights how underpowered my end game WW barb was/is.
I haven't pushed the pit yet, but just finished a lvl 100 pit without breaking a sweat.
