@deribus I'm glad you asked.
1- It would buff T3 mobile artillery, which are currently under-used. (Although I think the main issue is their extremely low HP, this HP issue can be mitigated with use of shields. Their damage is low, but their damage radius is very good which mitigates that. That basically leaves the range as the only problem.
2- This would serve not as a nerf to battleships mainly, but as a modest hedge against their domination against bases.
3- T2 static artillery seem relatively balanced (aside from their weakness to battleships) and so changes should focus on requiring minimum changes to them.
Regarding #1 in particular, I've been sure to watch ALL the LoTS games on Youtube. These games surely represent the top tier of play. In my view, it's pretty clear that direct combat units of all tiers (tanks, T2 tanks, T3 bots) take precedence generally, and only in specific situations do the 'support' units such as MMLs and T3 mobile artillery warrant consideration. Hypothetically, the game could be balanced in the reverse, that mobile artillery are always better than tanks, except in rare/specific circumstances.
I'm not asking for a paradigm shift, just a modest adjustment.
