Strider should initially be hostile

The Strider is nice, however it feels like the nether is almost a little too homely. The Strider I think should be a mob that is a initially hostile until tamed. This would be the first hostile, tameable mob, and would still give a little challenge to the nether. I suggest that it can spit fireballs similar to the ghast, or have a lingering effect that Burns/poisons the player.
