I feel like few heroes shined in 5V5 but not in 3V3
Lyra - Crystal Lyra is really scary, I went pure crystal as Lyra and she is really strong.
Make sure Lyra is played as backline. Still strong as a Captain. I feel like she is the strongest captain in 5V5 and 3V3 too.
Samual - A monster truly, Sustain health with life steal, huge damage with A + B and does huge damage especially when the opposing team are bunch up together.
Grace - I prefer playing grace as Weapon and she is quite good as a laner.
Koshka - Powerful, with the right captain she can go on kill spree and easily take out any laner and I feel like she really powerful in late game. Just don’t go in enemies’ crowd. Pounce attack, flee and join back
Lorelai - Effective as captain, good crowd control. I prefer using Lorelai against Flicker. I never seen any crystal Lorelai.
How about your heroes and your opinions on them?
