A lot of people hate leader powers because of failure exploit them at the right time I feel. However there are some that just are too limited and low damage.
1. Enduring salvo. This leader power is extremely critical for Jerome since it is one of his only offenseive leader powers (considerably his only), however it does little to no damage and the inspiration doesn't help.
2. Mass cloaking. I know it isn't exactly considered an offensive leader power, but this needs to be looked at. It is noticeable how nobody buys this ability because it is almost never usable. Sure you can target detect units to help make this work, but by the time all the enemy detect units are destroyed all of your army is already halfway gone. Also this leader power is only available to Arbiter and Shipmaster, two of the most offensive leaders in the game. This leader power it seems is only ever good for defense because that way the enemy can't just pump nightingales or place a watchtower to constantly detect you.
3. Ark defense. Just like Jerome, this leader power is critical to Anders because it is one of her only, if not only, offensive leader power. I honestly feel that this is a pretty good leader power itself but it takes too long to get. By the time it is available for purchase, people are already getting vehicles which this ability is useless against. If it could be received earlier it would be great in backing up Ander's marines because it is very effective against infantry. I think it should be swapped places with protector sentinels because protector sentinels are too expensive I feel to be viable when you can get them so early whereas they can be produced later more effectively.
4. Napalm missiles, These should do more impact damage because it seems like Kinsano is to weak against air and I feel this could help her a bit. If not this then the flames left behind could use a buff. This ability just needs an overall look over.
5.. EMP MAC Blast. As much as I love this ability, it debatably needs a look I think. I love how enemy vehicles get stunned and take more damage, I just think the direct damage could be increased a small bit. Really I just needed a fifth answer and this was a little forced because I feel the debuff it gives enemies is deadly, but it does need a damage increase still.
