Premium mounts questions

[ilcontegis]

Hi guys, maybe because of my English I cannot understand very well the description of the mounts. Can you help me?

There are 3 type of mounts:
1. 2400 ximerin
2. 7200 to 9200 ximerin (one mount in each realm)
3. 12000 ximerin

I can't understand the differences. Except the price, there seems not to be any improvement (eg. being faster, or have more life or have the ability to attack etc...).

Most important thing, I buy once and I have them forever or every time that I dismount I need to purchase again? Can the horse be killed? There is a specific lifespan of the horse?

I am willing to spend my money once to buy a horse to be faster but I cannot effort to repeat every time.

Thank you for your support
