Maybe in the past, where game was somewhat balanced.. with rewards, formulas, gear etcRekindling the fort fight fun isn't a good enough reason?
That being said, thankfully there still few people after that, even though Inno doing its best to kill them all.
Hail Inno! (or MTG now?)In a timeline where workers and advents pick Damager because it gives higher personal rewards, no, it isn't.
Main reason of higher rewards for Winners is to encourage a "proper" battle where both sides doing their best to win.I really would strongly recommend just giving the same rewards to people on both sides, regardless of the outcome. Otherwise, this whole idea risks becoming a farcical exercise.
But since Attacking is ridiculously easy (Intentionally by Game mechanics + much easier LoS control) and Defense ridiculously hard.. then add Randomness on top of that.. Why bother to Defend? Especially if u don't know for sure that there will be someone who will Lead the battle, which is a rare sight?
