Well the thing is you don't need to ride all the time, just on the open maps and especially in the evening when we gather up. I can't expect people like Bruno (leve 35) to respec but they could make a STF on a rouncey at least so they can ride with us, nothing expensive like Mamluke Horse.
Oh and I myself thought about balanced build so i can do both 1h cav & lancing. Switching between different styles makes it less likely to get bored with it, you can always just use a different outfit/weapon.
