So i've recently started a
CSM army and from what I have, i've come up with this list. Now I don't want to be uber competitive (which is nigh impossible for them

) but I don't want to get stomped at every turn. I want to know where I can go from here with improvements (I don't want to run any daemons apart from a prince). So this is the list:
HQ
Chaos Lord - Termie armour, MON,
VoTLW, Gift of mutation, Blight grenades, Sigil of Corruption, Black Mace and Chainfist [225]
Elites
Chaos Terminators x 5 - MON,
VoTLW, Icon of Vengeance,
CB/Power Axe, Combi-melta/Power Axe,
CB/Power Maul,
CB/Chainfist, Heavy flamer/Powerfist [271]
Troops
Plague Marines x 7 -
VoTLW, 2 x meltaguns, Champ with combi melta, melta bombs, Icon of Dispair, Rhino w/ combi flamer, destroyer blades, dirge caster, havoc launcer [297]
Plague Marines x 7 -
VoTLW, 2 x plasma guns, Champ with combi plasma, melta bombs, Icon of Dispair, Rhino w/ dirge casgter and destroyer blades [ 285]
Fast Attack
Helldrake w/ Baleflamer [170]
Heavy Support
Forgefiend W/ 2 Hades Autocannons and additional ectoplasma cannon [200]
That's got me on 1,448. Should I bulk up on upgrades to fill the points, drop somethings to add in more? What I have to choose from is:
2 sorcerers
Daemon Prince
26 Marines (6 with meltas, 2 with flamers)
What else I should I get to bulk up on?
