I prefere not to stop Ressources zapping, but ....
As it seems, we won't be able to zapp ressources anymore, and personnaly as many here I never liked DE Zappers, they drive me mad and they are the only ones that I take my time to prepare and make on them a revenge attack, but on the same time, stopping the DE or other ressources zapping could be done with a different way.
Why not to create a building a kind of lightining rod , which has a small coverage, and once placed it will stop zapping effect ?I think that such building presence is more interesting for game play, then completly stop ressources zapping.
This building will be HIDDEN Like tesla, with a small range once placed it covers from zapping...It's presence may change the strategies, because you can place it to protect the DE, or other buildings like Anti air defense etc...
For level 1 it protect from 1 spell, level 2 from 2 lightning spells and so ON.
I really find that more wise because it add some strategicall choices and more excitement to the game, cuz in clan wars some players who hit with 3 lightning the AAD will maybe face this lightning rod and fail their attack etc.
It will add more excitement to the game.
