Well, we'll maybe have to agree to disagree here. A lot of their errors last season were on the throws.
I'm afraid we cannot agree to disagree for the simple fact that protocols shows (not to mention the videos) you are wrong. Besides showing they they didn't have many errors overall, as you seem to think, you will also see they had positive GoE's for all their throws,
in all competitions last season, except one throw in the LP at the Euros. I'm not counting the 3STh they missed in the end of the LP because Fedor toe picked the ice during crossovers before the throw.

Same during 2013-2014 season actually. They had 2 errors during the whole 2013-2014 with the 3FTh. Once in the LP at Skate America and the second time in the SP at CoR.
You might not like them but their throws are their most solid element really. Their weakness is the twist because it was 2Tw before and now is 3Tw level 2 (sometimes not very well performed either) and some of the lifts. Although they have worked this season with a great italian WC roller skater on the lifts.
As for Trankov what I think I don't like is that he doesn't conceal his effort and he often stops to see how Tatiana does rather than just smoothly moving on with the choreography.
I don't know what you mean really? The partner should wait for the partner and get the right timing. None of the pairs does what you seems to be saying.
She gets great height, yes, gets excellent positions yes but almost half her landings are always two footed. So excellent technique no, but impressive to look at yes.
I'm not going to bother with 2011-2012 and 2012-2013 season now, but just having a quick look at their protocols from 2013-2014 season I can tell you their throws is again one of their strongest elements. They skated to: SA, NHK, GPF, Euros and Sochi. They got all +3 for the 3LoTh and +2 for 3STh in all competitions, except 2 times: the 3STh in the LP at the Euros where they got all -3 GoE's and a little bit low GoE's (although still positive) in Sochi during the LP because she slightly touched with the other foot during the landing of the 3STh.
I think you have a strange way to calculate how "often" these pairs make errors on their throws, and how "half of Tatiana's landings" are two footed.
Maybe you remember all their errors, like the SBS jumps, and you're mixing them with throws?
