If i understood correctly, you play with 4 friends premade. That sounds like the best environment to have teammates letting you smash thing for that extra mana regen and heal cooldown. Do yo actually get to do that? Also, does his passive produce mana from Wit's End's magical damage proc?

In practice, at higher levels, you don't really need the mana regen. It's extremely useful to buy a Fiendish Codex for late laning phase, but besides that it's mostly irrelevant except in prolonged sieges, which aren't the same as steamroller-like pushes.

I've never found a chance to try to push through to nexus. There's always better objectives to shoot for, like clearing large minion waves or stealing buffs. Taric is outrageously good at tanking towers, though.
