VCL Incentives vs Region Lock

Would you rather have what Riot have proposed with region lock players or have Riot give incentives to have local players?
Suggestions:

1. Have a % buff on the final placing prize pool based on the amount of regional players (# changes depending on region)
2. maybe they don't add skins or charms, but they do add sprays or calling cards for challenger or making it to ascension tournament & teams with local players receive higher % (# changes depending on region)

region lock.

• better to enforce the growth of t2
  incentives dont always work in practise
