She's easier to deploy but she's still very expensive, which is rather bad for a melee operator that cannot be healed and unlike Hellagur, does not heal passively when idle and requires her skill to be active to heal. Vulcan's an island, and that's not good for a Defender that has lower defense than normal, and no atk speed buff to help her out. Again, very, very few units in this game are actually dogshit, but Vulcan not being dogshit doesn't mean she's good and oftentimes she's simply too slow to deploy for maps where you want to set up fast. She has a myriad of issues other units don't have in exchange for a smattering of positives and powerful healing, but only while her skill is active, and she relies entirely on that skill. Maybe pair her with Liskarm, if you could get her to really high skill uptime via Lisk's talent, she'd work a lot better. Totally forgot Liskarm, guess that has to be pretty precise and get combined with Saria's S3.
As for games, not really, sorry. I like Dragalia Lost but that's about it, most other games like FEH have lost my interest over the years. Probably would be better to either emulate something nice or just play a PC or Console title.
