Having been the victim of this kind of behaviour,I feel something should be done about it,but not quite sure of what the solution might be.
I could be way off the mark here,but don't believe that the influence that is awarded from the battle is of any real consequence, if those are the points to which you refer, but when an event is taking place particularly when its inter kingdom, there is a legitimate reason for hitting tiles.
However I remain bewildered by the behaviour of some players who will chase down weaker players,when no other point event rewards are running, when their actual losses in doing so are more than they gained, the same with attacking inactive or even active towns, for what must be paltry amounts of resources for them at their level, especially as I wonder what effect this will have on anything they need to do.
I understand that its probable that you attract more attention as you progress, because updates get more expensive, you move to places where the tiles hold more, so you risk more troops maybe at higher levels, so the reward for a tile hit is much greater.
I remember a time when I was in the forest, yielding from a tile in sharp short bursts, and someone messaged me with ,don't send tier 1 troops send tier 5, which was both a telling and strange request,they should have known it was impossible for me to have such a high tier troop.
They must've scouted which you cant see ,could they have got there if I was using tier 5 troops? possibly / possibly not.
As you say it just drives away players who might want to play keep playing but realise its like hitting your head against a brick wall , when you come up against players who can do this kind of thing not because they are good at the game or any more skilled, but because they got a fat wallet and can keep paying for the latest upgrades, which just enables to do more of what they were doing anyway , but to more people and more noticeably
