20% accepted culture is of no use. Irish and Welsh cultures will never even reach 20% as the number of provinces with these 2 cultures are limited on the British isles only.
At most Bengali culture is accepted later on in the game when GB colonizes large areas of India in the 18th century. But GB can form Trade Company in India which will accept the Bengali culture and no unrest will be created.
Hence, I suggest to either increase the accepted culture to 50% or higher or remove this tradition and replace it with another more useful tradition like 10% siege ability for English tradition.
This is because I notice GB does not have any bonus for siege ability as it does not have the offensive idea if you play later bookmarks. And this will affect the length of GB sieges, thus slowing down its expansion.
