definitely better than the first, although that was also quite epic. and dalcde, from my experience the elemental arrow rate is faster than regular arrows.
Pro tip: Upgrade arrows and barracks all the way first. Then hit 0 ingame for auto arrows. Send units to keep your castle unharmed as needed, while getting mana maxed. Fully upgrade barracks and mass your strongest unit. This strategy is great for the first 9 or so levels, then you need to meld in archers and magic users.
