10% chance to get Lava?

So I know the chance to get Lava is 10% chance, but I am wondering if 37 failed attempts seems a bit excessive?
I have spent gold to cool down boss several times now my Roco is now level 18 player level is 14 and my only other dragon is a level 5 Leashy.
37 times not joking I about ready to give up on this... Because 37x for a 10% drop with no success don't even want to imagine who many times it will take me to get a dragon with 3% or below.

It seems I post this in the wrong area... Anyways 38x now

Up to 40x no lava dragon... What the fuzzels?!
I have decided if I get to 50x no dragon I am quitting... Sorry haypi it's a fun game and you can keep the $.99 I spent on a coin pack but if its this hard for me to get a new dragon the games isn't that great for me.
Why would I spend more money on a game that seems hopeless for me, I've done Lava boss 40x now and other people are getting Crystal dragon on the 6th try... Yes I know now I'm ranting maybe they are just the luckiest people around, maybe I'm just the unluckiest person... In my opinion and to validate this post for being in the suggestions area instead of the general here is my suggestion:
Make getting new dragons in a way of by purchase for example:
Defeat Leashy boss 1star = 1 Leashy coin, 2stars = 2 Leashy coins, 3stars = 3 Leashy coins. And then have a Leashy store area where you can spend your Leashy coins save enough coins say 25coins for Leashy you can buy the dragon higher level dragons would cost more coins and have different items also in the dragon stores to spend your ecsess coins like magic stones or something.
This way I or other people in my place don't have to wonder if our accounts are bugged, also it won't piss off in game spenders like myself, as of now been playing only a couple weeks only made one purchase but if I quit because of this stupid set up of me just being unlucky then there is no more money for you guys from me in the future.
Food for thought and 10 attempts to go.

41x

That is nothing compared to when the game first came out,
s2 players raging when they were on the 100+ try to get Lava!

Give it a few (to 100) more tries

Theres a guy in s8 that took him 120+ to get crystal and finally after he took that long he got Angelo in about 20 times then he got devil on lie hes 5 th try then got naughty in about 10 eggs

42x
As for 100+ tries to get lava that is rediculas like I said 50x I've had enough..

43x
