yeh not bad....i mean khan would be probs better but a tad more expensive in points but u get sum awesome rules such as outflank 4 army i fink....furious charge...he has his own powersword which intanst kills on 6's and bikers of over 5 count as troops....but thats enought bout him.
yes it a good idea...very fast and go were needs to be vry quickly and if their specialised then they can feasome such as tank hunters and like u said combi melta....bs of 5 probs not gunna miss and cause damage and u can get close and use melta rule because of bikes...ive tried a bike army be4..and is vry effective with the freedom u have. giving the unit hes with things like power weps melta bombs meltas plasmas and flamers u can go headhunting, tank hunting, overall, troop killin.
also, the model would look pretty awesome.
i wouldnt say captain.....more chapter master but if u have no points then hey so what but 4 that 25 more points then u get bombardment which can be a saving grace or the opposite.
the prob wit dat is uve musnt move to use it which will be the unlikly case if ur ona bike.
jus ma 2 cents lol.
hope i helped
