Disagree.
Base/default skins with chromas unlock through mastery? Yea, very agreeable.
Special chroma for certain ranks, events, etc? Yes, also agreeable.
Not paying for chromas ever? No, that's unrealistic cause Riot needs to make some money.
Paying for skin chromas is fine, but there should be the option to do something like:
"Unlock this skin and all future Chromas for this skin, 975 RP + 500? RP"
I think that's reasonable. Skins and champions are sold in bundles so why not make champion and chroma bundles too?
Additionally, I would rather go to the store and pay $100-200 just once to have all current + future Chromas for every skin I own and will own in the future unlocked instead of having to buy all these little sets.
Honestly, I will not buy any chromas if they ship as is. It is not because I think the current price is unreasonable or that this it a good initiative (let's face it, this is long overdue). I won't buy the chromas simply because I personally do not feel they are worth it.
Do they look nice? Sure, not all of them but overall they look nice.
I've already chosen to support Riot and League of Legends by buying many skins and introducing people to the game. Even if the price of a chroma or set of chromas translates to about $1, that ain't worth it for me. If the chroma changed the colour of the champion and some of the VFX, then yea I would totally buy some.
If doesn't even have to be fancy VFX changes, just re-colours like on the character model. I've seen Blitz hundreds to thousands of times. If you want me to buy a chroma for his derpy ass, then that Red Blitz better have red lightning for Static Field and red sparks on Power Fist.
To me, that doesn't seem like an unreasonable request or expectation because Riot isn't the same company it was when Green and Pink Taric were considered perfectly legitimate full-priced skins.
