I personally decided to already claim my tokens. I sleep better since I know there are now inside my ETH wallet, safe. My EOS keys are already registered and pointing on my ETH wallet.
I did the whole process using Metamask. I have explained how to do it in this post:
EOS Launchday - Token Registration - Are your EOS tokens registered ? How to do it with Metamask

The high Gas fees you are mentioning inside your post are those you are paying for your transaction through the Ethereum blockchain as the EOS token is based on an ETH smart contract and is hold inside the ETH network. The only one you should blame for these high gas fees is Vitalik Buterin.

Any transfer of tokens inside the ETH network is in average 10 times more expensive than an ETH transaction. The good point with Metamask is they will calculate for you the right amount of gas. If the gas is not completely used for the transaction, then, the difference will be given back to you.

The question is who will pay for the ETH network gas fees when the remaining unclaimed tokens will be automatically transferred from the EOS.IO's ETH wallet to the buyer's ETH wallet in late May or early June before being frozen when the Mainnet will launch ?

Have a nice day,
