I am heavily in favour of bringing some kind of collection power requirement back into the game. I say this as someone who bots 99% of the time. Currently the only way to get value out of extra/double cards is to either rent them out or delegate them to an alt.
However, excluding rented cards for this makes absolutely zero sense to me. Why would you actively punish people that rent to play. This is the only way people can get into Splinterlands without spending hundreds of dollars and with this proposal any earning potential for those players would immediately be destroyed.
The biggest issue I see with people that want to 'improve' Splinterlands is that they do not seem to understand that bots and new players are very similar in their behaviour. Lately all the anti-bot action has been hurting the barriers of entry for new players to give some extra crumbs to the whales, but that is an issue seperate from this proposal.
As I said before, bringing back a form of collection power restrictions is in my opinion a good step, just do not exclude rented cards from this. Excluding rented cards is an immediate no vote for me. Also maybe make the barriers dynamic, otherwise card inflation/deflation would ruin the intended purpose.
Completely agree about excluding rental cards!
