Like I explained in other topic, when they would just add new level to defensive structures, that would mean spells and troops would become obsolete.
Say they buff defense power by 10%-20%. Lower troops would not be able to survive the damage done by towers. So their health also needs a buff to survive and no, we don’t want to have new levels to realize that.
Spells also become more and less obsolete. When firestorm can’t destroy firebolts any longer and spells become too weak to do their job well, it’s also not good. When spells designed to kill troops are no longer killing troops, then spells are useless. So also they need a buff.
Maybe a good idea is not to buff anything, but let us build a few more towers plus obstacles and give 1-2 extra tiles for the path. 2-4 extra towers and 1-2 additional obstacles plus a slightly longer path, would definitely make some difference.
Sure, some of us would need to build new towers from scratch and start to forge those. It’s better than always use additional levels to defense. For starters there are too many levels on towers already. It’s nuts that some defensive structures need 17+ upgrades to get them max. We don’t want any more levels on top of that.
So when offense is OP, give us more towers and obstacles plus a slightly longer path. That would solve those problems.
