T1 arty Is currently usable as a longer range mobile tank with excellent damage, and while it can be out microed in small numbers on 5k ladder matches it is a massive problem in longer team game or even 1v1s (especially as the best counter for it is seraphim too) the arty is too cheap an can be overwhelming in Roanoke's abyss games as it can get into small roving bands and get everywhere. even if you build pd on the islands t1 can be out ranged and t2 especially aon can be overwhelmed. as gyle said on his channel something must be done as it can be too effective even in the t4 stages and it feels sploity.
as a balance change, as gyle said it needs to be much more expensive or stationary to fire so it cant be used as a tank in runby's
