Yes, I think ETH fees have a negative impact on WLEO. TVL and everything may look like Ok today, but I believe it could be much better with lower fees. The fees may not be very important if you already have, e.g. 10 ETH and swap it into WLEO and back. The real problem begins when you want to buy e.g. 0.1 ETH for USD, swap half into WLEO, and lock it all in the pool -- total fees in USD will be triple-digit now, I think. For quite a long time already ETH DeFi requires four-digits USD amounts to be barely profitable, and the situation goes only worse so far...
