I played 2 battles today. One against BA (with Ulthwé), one with BA (against Saranes crusade IG).
The first was a massacre (Assault Marines and Bikes + Land Speeders against Warlock + Mounted Guardians + Falcon swarms), Assault Marines were on foot, and the Warlock wiped them out in 2 turns. The Assault guys are still weak, not worth their points, they REALLY need the transports! The turning point was in turn 1 -when 2 BA termies (with captain) teleported next to my mounted Black Guradians (With Seer Council) and Swords of Vaul unit -the Ulthwé army also has a strategy rating of 5 - I won the initiative, get the termies (intermingled formation) with my two units, and break them in CC with my skimmers popping up.
Eldar are EVIL with their full move consoliation! The Warlock is a BEAST, against a CC type army it's even better The second was against a Saranes army -It's a SM + IG combination. There was a HUGE HQ formation in Landing Craft (!!!), Termies in Land Raiders, Mechanized infantry, Vultures and Warhounds (2 in a pack, and 1 lone one).
My BA Army was a fully drop/teleport army. 3 termies (Supreme commander, Captain), 2 tacticals, DC tactical in a Strike Cruiser, and planetfalling one Stormraven formation, with Whirlwind and Thunderbolt support. The dice was against me, i failed 2+ activations many times, etc. The drop was in the middle, next to the guys on overwatch. 3 drop pods hit the LR-s, even killed one, with the termies inside
The stormravens and the Orbital Bombardement hit the Warhound pack, but killed none of them 
The vultures hunted down the stormravens, the mechanized guys marched next to their Blitz, the Warhounds killed a lot of units in the middle, wiping out one of the Tacticals. Next to the Blitz, the Landing Craft with the HQ landed (I rolled 1 for my Tbolts, to activate previously), assaulted the Whirlwinds, let only one broken survivor
In the Second turn my termies arrived, 2 fomations together with a captain get the landed HQ + the Mechanized Company (intemringled formation), killing 13 units, losing only 3
Both of them fled. The other termies with my Supreme Commander get the Land Raiders (with termies inside -enemy BTS), with the DC and one tactical formation together. They wiped them out, without leaving a chance to them to disembark The game was a finsihed, becasue it was late.
So my opinion is a Terminator unit (With a COMMANDER) is a big thing, if you play with a drop army! It helps you to correct the scatter of the drop pods -but at least 3 is needed, so one can operate with the dropped guys, and the other 2 can kill anything ,even an Emperor titan!
the Saranes list is too strong, with strong IG units, 5+ CC, 6+ save? WTF?? IG in Landing Craft? WTF??
