With all due respect could you define what you mean by "solo friendly"? Because to me, players are not solo unless you are able to:
Hold 2 battlefield objectives alone
Run all the boxes to level your keep alone
Spawn a ram and cannons alone
Take them to enemy keep alone
Knockdown both keep doors alone
Kill the keep lord alone
Capture the keep and all flags alone
All of this while defending yourself from enemies even if its 1 or 2 wbs. You must be alone!
Now if you can do all of that alone then i will happily call you a solo player. But until then you have to recognize that others are out there and the reason that you get renown points for capturing a keep or a zone. It is because others were helping. You did not do it alone. So to say your a solo player when really others helped you get this renown points seems inconsiderate and disrespectful.
Anyone can be in a 1vs1 fight and kill an enemy player. Even i can. But that doesn't mean i gloat about it or try and label myself as a solo player. That is just an ego that some players have.
