The only thing a railgun will not consistently take out each turn is a Land raider. The strongest Gunline shouldn't need to be highly mobile, you pack enough Alpha strike punch to remove the enemy mobility. Of course Railguns are not as good whilst shooting infantry, the same way Lascannons are rather inept against Infantry. They should be used to take out Heavy armored stuff, like Rhino's, Terminators etc. Once those are all dead, then you can turn them on infantry. Let your Fire warriors , which have a damned good weapon, and most Tau seem to want to go to BS4.
It just shows, just because a unit can get cover doesn't mean that every unit in the army should need it to be able to actively cross the board. If your army can consistently kill off anything without a cover save, your army is broken as hell.
The Railgun is costed proportional to its efficacy compared with the Lascannon, which can be spammed quite readily, or various other vehicle mounted weapons which can be fielded in equal or greater numbers.
Rhinos are tiny models for what they do, they're quite possibly the easiest tank to hide in the game. Tau already have highly effective alpha strike capability against Rhinos anyway: Our basic weapon can take them out, and the battlesuit Missile Pods are even better at it. The changes outlined change little about that, Rhinos just don't last long against Tau without their little coversave-smoke launcher manoeuvre or their aforementioned size advantage being able to take greater use of terrain than practically every other vehicle in the game.
Fire Warriors at BS4 made sense to me originally, but it doesn't anymore. They're not trained to the extent that they're the same as Space Marines, nor is their technology capable of controlling their own bodies (which is the case for battlesuits).
All your complaints about the Railgun are in-game right now in effect, the buffs in other areas are to make up for the fact that the Tau are overpriced at the moment in many areas (Crisis suits, pathfinders, Stealth teams, Skyrays, Devilfish to a certain extent). Admittedly, I have gone overboard in some areas, but this is what this discussion thread is for. Railguns aren't an area where I think that is the case though, they remain well balanced according to their costs.
The army can't consistently kill off anything without a cover save, and practically all armies have weapons that render units stuck in the open as extremely vulnerable. Tau don't even have the most devastating or numerous weapons in that regard either.
