2 main problems:
too many terminators
too few troops choices
fewer little problems:
in my oppinnion they normal
CSM are not very usefull like this. i would use 10 instead of 16 and bump up your charging units a bit. furthermore they definitely need the plasma guns.
autocannon + lascannons on pred is completly useless choice, either go for:
- mobile anit tank, static anit horde -> twin linked las + heavy bolter
or
- anit tank platform -> 3 lascannons (this is what i would go for considering you already got a havoc squad with 4 heavy bolter)
your are lacking anti tank. for example: at 2000 points there is no space marines list that doesn't run with (at least) one land raider.
hf getting that killed.
you are lacking
ap:2 guns aswell.
in general you are lacking usefull heavy and special weapons.
you tactics wont work out like this. if you deep strike your terminator their just fodder.
the one rhino (or maybe even 2 in some variants of your list) will probably be shot far from the enemy. any result except shaken will be fatal for your plan.
even if by some miracle the rhinos arrive safely (which i very much doubt) there are not enough guys riding them the be a serious threat (at least at 2k points).
if you can't charge enough (or in worst case scenario any) your terminator will be left out in the open with no support.
there are very few lists (in competetive play about none) that can't deal with 20 deepstriking terminators in one round at 2000 points. just look at how many vindicators and the likes are used these days.
furthermore you have to rember they can not charge when deep striking, so they can't hide in
cc. they will get shot at with every gun of the enemy's army and getting charged afterwards - result: ~800 points gone.
that's about it....
for now
