I had hopes for opening Electrum channels but have to let it go because your post took my confidence away. Three Electrum channels will not be cheap. I will read about the Electrum routing issues, when I am ready I may potentially select a new option. I have one problem less to think about because I have a fully synced node.
You'll get 10 merits if you open a lightning channel. Since you're running Electrum, you can open up to three of them and get 10 merits for each one. More channels = better.
Channels are not cheap to open so this is a good incentive for opening them.
Besides, Electrum is known to have payment routing issues with only one channel, as I saw for myself some time ago. So better to open more than one channel.
