min da to get the wavz at cheapest cost is useful to 'bulk' up army
but i prefer max da with exarcg with pw&ss... mainly for the 5+ iv save... stick a lord in there for fearless and some teeth and they can be a pretty good all round unit... dont underestimate bladestorm ... the lucky 6 gives ap2 and can fry anything up to T5 relatively easily...
im prefering spinners to serpents but most ppl seem to play a mix...
a basic storm guardian squad with two gunners and a spearlock is now a reasonably pointed anti-tank unit with some anti infantry threat.. and again they can have a wavz...
tbf our group has turned the wavz shield into a 'ONE USE ONLY' ability because it is a bit too good...
hawks drop on a sixpence as long as you have 6, spiderz are awesome with the new monofilament rules [why spinners are so good aswell], avengers are better, guardians are better, gjb are now much better in offence but can still be used to steal for 51 pts instead of 66 ... bargain, walkers are awesomely better... why other vehicles cant have power fields gawd only knows... ghost walk matrices can give eldar vehicles a real edge though why the cost more points than there tau =.... again gawd only knows...
prisms are better... they have three shot options and keep the 60" range... though why they cant have a 'shield' as well is another mystery, falcons suffer because everything else has got better in comparison, and again ... no shield... !
shining spears and scorpions can be useful and are marginally better... both have outflank and spears can get hit and run...
banshees and quins, well... if your not a purist they make excellent DE whyches, which for 10pts naked and 12pts with haywire grenades, [DE allies are great ... especially VOIDBOMBERS. ! ... they make eldar flyers look vaguely pathetic... ], otherwise your close assault girlies are staying in the army case...
at 1750+ you can run mechdar with 6 0r 7 serpents, 3 hs skimmers to taste and some fa slots,
guess my cheesiest 1850 orbat is actually DE with ELDAR allies
3 voidbombers for AT, 3 venoms with double cannon and born with double cannon for AI/AM, two mini whych squads on foot or with double cannon venom, {oh yes they really do look like quins dont they}, HQ to suit ... usually cheap as chips sucky... and battle brothers: 3 TLBL serpents, two min or max DA with autarch or lord or SS, one 6 man dragon unit, ONE SPINNER for rear area support... ST7/8 TORRENT, thank you ! and or ONE unit of SPIDERZ or Spears to give some reserve ooomph... lots of goodies...
