Wall levels and Earthquake spell
So it's kind of frustrating to see your hard earned lvl 9 and 10 walls flored by 4 lvl 1/2 earthquake spells. And in my opinion that seems a bit unfair.
Earthquake spells do up to 25% of damage per spell depending on the level. Which gradually diminishes on buildings (100%>75%>56,25%>etc)
So here's my idea, you actually need better level earthquake spells to destroy higher level walls.
The earthquake level
1 14%
2 17%
3 21%
4 25%
So the wall's capability of defence should be (level^10)-10 of it's actual level
I'll start at wall lvl 6
6 = 50%
7 = 60%
8 = 70%
9 = 80%
10 = 90%
11 = 100%
For lvl 6 walls 4 lvl 1 earthquake spells will do the trick, as 4x14% damage cuts 56%, 6% over the required destroy ratio
However the same 4 lvl 1 spells on a lvl 7 wall won't bring it down, because you are 4% short of it's destruction criteria. Thus requiring at least 2 level 2 earthquake spells.
This goes on. For the level 8 walls, 4 level 2 EQ spells won't bring them down 68% out of 70% meaning you'll need at least one donated lvl 3 earthquake spell.
For the level 9 walls 4 level 3 spells is sufficient (4*21=84%/80%).
However for the level 10 and 11 walls you need 4 maxed out EQ spells.
This certainly brings some more challenge into just dropping 4 EQ spells and trampling someone's base. Really requiring people on higher tiers to have CC donation's in order to execute a succesful attack
Sorry if i wrote some things a bit sloppy. But this is the concept i'm thinking about
Fellow clashers what's your opinion.
