have i understand it right and the level didn't count by the tier-upgrades? and is it a good idea a bit for the upgrade invest in level bevore the 'price' per Stat get up?
thank you all for your answer
Level does not count towards your Tier, only Strength, Defense, Health, and Speed So yes, you should get your level up to the point where you can train before you go up a Tier
I personally don't spend my XP on Health, as it is more expensive than the others; I train Health at the Training Centre instead
Hope I helped you out ;)
