Well for those of you with it well done, for those of you like me trying for number 10, the question if your a gold spender or contemplating it is is it worth it?
Well if you're in it for the long haul then maaaaybe. Certainly with its own stat increase becoming a 367 attack and 208 def vehicle is in itself worth over 950 gold to buy as a game item. BUT you can spend 950 gold to open only 31 boxes (allowing for resets... about $3 a go) and not be guaranteed, but it is guaranteed if you buy a 950 gold item. How would you feel spending $95 and not getting it? DON'T unless you promise NOT to complain on the forum... it's gambling so I suggest stick to medium chances and pray if you don't have deep pockets and a calm demeanor!
Also lets look at the reality of what does +30% ground really give a long term player?
Well nation bonus aside and boost aside it just makes the most powerful ground attack value 45.4 and defence value 33.8... lets see...on defence 4 cash ships beat that... some planes come close... and the attack? one plane and one boat beat them, both with lower cas rates, but it does make a German player 'nearly' compete with UK and Russia. So worth throwing hundreds of gold at ? or just a few gold to change to Russia or UK... only you can decide for your self... definitely long term not for me.
Then there is the gold spenders like me and I have dozens of good powerful crate ground units which would boost my attack and defence massively if I got this.. but a year from now when 99% of my units being fielded are ships and or planes??? not really.
So I hope to get it (Fingers crossed) but not paying for a chance at it... bring in a +30% Sea unit and I'd throw 1000 gold to get it and shut my mouth if I failed! (Secretly I'd cry all night but then it's a risk)
