What if I pick Biloir first and they counter pick Blade or Locke last?

Ask teammates to scout the map to avoid engagements.

Looks good

As the ancients said, 'Know yourself and your enemy, and you will never be defeated.' If you encounter Locke, use Bilor's river mobility to avoid combat; if you face Blade, you need to use the second skill's healing and marks to suppress them early on and prevent them from snowballing!
