FFXIV's Bastion Tank: Dual Shields and Guns Test Steam Deck's Limits
Of all the things that could push a Steam Deck to its thermal limits, nobody expected a tank job to be the culprit. But FFXIV’s Bastion, unveiled at the Evercold expansion presentation at the Berlin Fan Festival, is exactly that: a tank that dual-wields shield-guns, fires them as projectiles, then charges into melee range with enough particle effects to make a Pictomancer jealous. For players on Steam Deck, ROG Ally, and Legion Go, the Bastion is not just another class—it is a stress test for whether handheld PCs can keep pace with modern MMO job design.
Shields as Projectiles, Battery as Sacrifice
The Bastion’s trailer shows a combat loop that alternates ranged volleys and close-quarters shield slams, each transition layered with magitek VFX. Compared to Dawntrail’s Viper and Pictomancer jobs, the Bastion appears to demand more draw calls and more persistent GPU load—precisely the conditions that drain portable battery fastest. Steam Deck users running at 30 FPS targets may need to drop resolution to avoid stutter in eight-player trials, while ROG Ally and Legion Go owners with higher TDP ceilings will have more headroom but face thermal throttling during prolonged raid sessions. The good news: Dawntrail’s streamlined moveset design—fewer buttons, simpler combos—carries forward to the Bastion, meaning controller layouts and Steam Deck back paddles should handle the rotation without gymnastics.
January 2027 and the Second Job Question
The Bastion starts at level 90 with a job quest beginning in Limsa Lominsa. It is the first of two new jobs for Evercold, with the second (expected to be a DPS role) coming at the Japan Fan Fest. Square Enix has until January 2027 to optimize the Bastion’s asset streaming and cull unnecessary draw calls for lower-end hardware — and the Switch 2 version’s launch on August 4 will offer an early preview of how MMO performance translates to portable hardware. The handheld audience will be watching those patch notes more closely than any other: if the Bastion runs smoothly on Deck at launch, it signals that Square Enix is taking portable performance seriously. If it does not, the precedent for future job designs is worrying.
