whilst playing the demo (yeah i know, but im gettin the game from "santa" in a few days) i noticed that i was using dreadnoughts alot untill i watched my dad whom of which was using just preadators.
ive sort of come to the conclusion that both have their merits and flaws so here i go (hope it dont sound to newbish :bandit: )
Dreadnoughts: dreads are and always have been my fav. they have obvious advantages over Preads in the fact that they can get into CC and deal out a nice amount of Damage but when it comes to firepower they are formidable but no where near as good as Preads and as for the amount of damage they can sustain, its good but not as good as Preads. the best weapon i find to arm them with is the assault cannon as i find that it will hit more often than the lascannons and fires pretty much non-stop. the Hellfire dreadnoughts are alright in a defensive situation but i find they are too slow and are out paced by everything else on the advance.
Preadators: these are VERY dangerous! there are several diffrent weapons options (as you know, Dur!) but my fav is making squadrons of Preads, 3 in each two with twin-lascannon turrets and heavy bolters and one with all lascannons. this is a very nasty squad to run into as it can tear apart armour and infantry to no end. another one i like to use is a single pread armed with an auto-cannon, heavy bolter and lascannon, wierd yes but very versatile. or you could arm them with autcannon and lascannon sponsons.
Overall the Pread comes out on top, with it superior speed, firepower and damage control, i think its better investing in these than masses of Dreads.
these are ofcourse my veiws so dont think im trying to tell you how to play, i would liket to get your feedback on the topic and see what you all think
