2.5 Pally/Purifier List (Blastphemers beware!)

Hello Brothers,
I am still new to 40k and have received some aid from other Brothers on a 1500 list. Now I have attempted a 2500 list, my only concern is lack of maneuverability and/or "big guns" Here's my list so far, any suggestions would be appreciated.

Draigo
Librarian
shroud, sanctuary, quicken, MoT, staff

10 paladins, totally wound allocated x2
1 psycannon hammer
1 psycannon MC hammer
1 psycannon halberd
1 psycannon sword
1 sword
1 halberd
1 mc halberd
1 hammer
1 brother banner
1 staff

10x Purifier Squad x2
3 psycannons
1 MC-psycannon

Total-2470

Again, any suggestions would be appreciated.
Thank you Brothers

You're missing a second troops choice.

i believe its 2 groups of 10 paladins so he is ok with the troop choices.
What i would suggest is to maybe loose the purifiers and add some vehicles, land raiders stormravens and such, they should add a great deal of mobility and some much needed multi melta/lascannons.
But thats just my opinion

You could drop your paladins down to 7 (and you can still keep your apothecaries), attach hq's to each and then put them in LRC's. That way you still have paladins, but now they can move where they need to without getting blown up in the process. Add a psyfledread and maybe some interceptors with your last 500ish points.
