Draco nerfed

So I was recently playing fc team and I knoticed that my Draco lv47 usually one shots snow with fireblast and wildfire can take out two lupas at the same time. Recently I've knoticed that I can only nearly killed snoe with fire blast and nearly kill lupas with wildfire. I did not change anything about Draco and the monsters haven't gotten stronger in fc team. I just wanna know what's going on:/

Maybe you had a claw(+10 attack) on it? Then you took it off?

No it always stays on my draco

Land on the debuff crystal and get lowered attack maybe? Has this been more than once?

For like 3 times now:/ none of you are experiencing this problem?

I noticed something like that too...when my Flight attacks a snow
Monster in a Map like 4-5 times ( always same lvl and same monster and same attack ) it does like always hits with different dmg.
For example:
1. Fight: First Hit does like 70 dmg
2. Fight: ,, ,, ,, ,, 63 dmg
3. Fight: ........ 57 dmg

and so on

That happens with me too with draconius... i hit a monster wit fire blast nearly like 45% is left from his hp and next turn i barely get his hp to 10% o.O
