Damage mods are getting a pass, and the LR, and Assault Rifle weapon class have also been confirmed to be getting another pass too.

EDIT: The goal of these balance passes is to both increase over all weapon balance and increase TTK a little.

I wouldn't count on a vehicle rebalance until much later after 1.8.....

Remnant went on a posting rampage a little while back - spilled quite a lot of interesting stuff.

EDIT: The LR and assault weapon class passes were specifically confirmed in different threads, though.

I believe a dev said that amarr and minmatar vehicles are NOT coming in 1.8

However, considering that they said they "need to check before confirming or denying", I would say 1.9 is a safe bet.

Total speculation?

1. Damage on Swarms will likely increase. They are meant to do consistent damage rather than burst yet cannot really overcome passive Shield Regeneration. I see the damage increasing while the range stays the same.
2. Militia Tanks are going to be hit in the PG/CPU department and Militia modules are likely going to be less effective number wise (less effective rather than just having a worse active to cooldown ratio). Other than that, no real change to vehicles.
3. Maybe not in 1.8, but I see damage of the weapons going down across the board. I foresee them making the Assaults and Commandos do more damage by investing levels into them (3% bonus damage for Hybrid Weapons per level of Caldari Assaults, 3% bonus damage to explosives and projectile weapons for Minmatar Commando, etc) and then lowering the damage of the weapons. It gets rid of the "Slayer Logi" problem and doesn't change TTK. They are already doing it by making equipment less effective and giving logistic suits bonuses for certain types of equipment. Makes sense that it would happen to weapons next.

Be well.
