And if you're using destroyers as tanks, you're doing it wrong. Necron warriors are your tanks. Destroyers are your tie-up and mobile anti-melee ranged unit.Most players are forced to get destroyers to keep up, because any race needs tanks if they want to survive, its just that Destroyers/heavy destroyers are definitly not the best tanks in the game.
Alternatively, if you're suggesting that every race actually needs durable vehicles to win (as opposed to durable units in general), I'd introduce you to orks and DE. A very large number of players don't build vehicles unless they need to counter heavy weapon masses or need a transport. And the destroyer fits the first category perfectly
Destroyers have a very respectable 41.3 dps across the board to all infantry, on a platform with 30 move speed, when *all* ranged infantry that can equip heavy weapons has in the ballpark of 1-2 dps against it in melee. Notice how the destroyer is the perfect tie-up for heavy weapons who are the only things I see people complaining about with necron warriors?Also the fact that Destroyers/Heavy Destroyers get tied up in melee is actually more of a disadvantage then an advantage, because they do far more damage in range then in melee. Unless you are using them to up ranged squads in melee combat (??????) the other races tanks are generally a lot better. It may do nice melee damage, but its a single unit and not a squad. In fact most inf squads could most likely out melee it, (apart from maybe obliterators)
The relic wiki is borked, since it suggests tying up destroyers (which unit's going to be mobile enough to do that except maybe stormboys?), then in the very same paragraph tells you to be wary of your AV getting tied up and killed in melee by it.
The destroyer, for all intents and purposes is a wraith with brilliant shooting, faster move speed, way more durability, but no detection or decapping potential.
Orks get one teleport for one squad, SM gets the deep strike and a slow teleport on termies. Chaos gets a deep strike on some units and a teleport on oblits. Barring any lapses in memory, that's pretty much it. That's a far cry from an early-game deep-striking melee unit, a hugely teleporting hero, and all infantry being able to teleport back to base.Any race can do the same, not just crons.
Yes, other races have mobility options such as transports, eldar scramjets, or IG tunneling, but these aren't an unstoppable retreat tactic that always works. They can still be countered and shut down. (Ok, maybe eldar scramjets are comparable.)
The one sentiment I can share is that the fotm issue certainly does affect destroyers a lot. Just as it affects pretty much every vehicle that doesn't have a flamer.
