in the best case scenario, with elemental focus and a critical strike you gain almost 10k mana back, thats 6,25% of our mana pool aka a chainlight or almost a healing surge

then they changed elemental oath to 5% haste so I'm only having 11,8% crit now, so about one of ten lightningbolts will crit

and on top of that your not doing that much damage by spamming 8k lightning bolts in pvp

not sure if thats worth a glyph spot
Unless there's a massive change to the way that elemental gains mana from fire spells or the numbers get tuned more clearly at 90, I really fail to see a way we're not going to have the glaring mana issues we had at the start of Cataclysm. Lightning bolt spam hasn't been a real effective way to deal damage since BC anyway... I'll take 1% net mana gain (and a "mana free" spell) over an empty mana pool anyday.

At 90, you'll have the potential also be doing 25% more damage with LB anyway to offset the damage reduction with the UE talent. Hopefully we'll be looking at an 88-89 level cap soon so we can see how ele scales.
