The title says it all,I kinda say that it is worth getting to 100 bronze/silver because you get Cr no matter what.But since,I'm not good at DTs and get t25/t50 I'm kinda like "Nahh,I can't be bothered to get to 100".And If anyone got to 100 just post what Cr you got.
Used more than 100 silver, no CR.
1x Lin Xia
1x Pr Hartnell
Around 20k clintz
+ junk like experience
Used 26 gold tokenz, no CR.
Plenty of experience, which is extremely aggravating to get on gold, since it's like losing the token.
I don't list bronze because everything there is close to worthless.
