Unfortunately, in order to improve skills you will have to learn and grow some braincells 
I can point you in the right direction! I actually learnt to export animations from Blender to Roblox recently, after solely relying on the inbuilt animation editor. Granted I had years of experience in Blender anyway, just not for Roblox animation.
First you’ll need a template rig to animate from within blender. This one is great (R15):
Although I see you are animating with R6, in which case, this looks good although I haven’t tried it.
To import Blender animations, you’ll need to install two plugins. One for Roblox Studio, and one for Blender.

When you install the plugin, you’ll then have to enable it in the same Addon manager list. After you’ve done so, to find this new Rbx Animations plugin control panel, expand the arrow on the top-right of the viewport and click the tab named respectively. You can also press [N] to toggle this inspector panel open and close.
This plugin essentially lets you export over animation data from Blender to Roblox Studio by converting keyframe data into an encoded string and copying it to your clipboard (it will be a very long string, for example ahem " b09sdA()_£*WQA(RIJbmdaklsfbq89-a£WRUB(){AEJRDfbuiwsumtbj4web09tibwas[0930230-429i5 " (not a real export) ) - and importing it to studio by pasting it into a script editor window that is temporarily opened by the plugin. From there, you can upload the animation to your inventory!
