In reality, you're better off taking a defensive weapon to Ala. The first time I fought ala, I didn't know much about him so I took a defensive approach, using a lance. Using weapons like Axe or LS is a bad idea for your first time, and surely if you can just strike and block enough, your teammates will hopefully do the rest. Just try not to die and keeping yourself, as well as your team alive. My first run against Ala went well and surely None of my team died, hopefully you'll get someone who's good with hammers.
