I am still hoping against hope that wotc will release ToB errata, but who am I trying to kid? 4e is clearly their highest priority right now, and they likely won't bother with any 3e material anywhere in the near future.
Just for completeness, I am wondering if there is a collection of submitted entries detailing what parts of ToB are erroneous/problematic, as well as proposed solutions for them?
For instance, the warblade will find it difficult to acquire a 3rd lv stance unless he multiclasses in 2 other lvs before warblade4, spends a feat on martial stance or uses his 10th lv stance allotment to take a 3rd lv stance instead, none of which are particularly optimal. Thus, it makes sense to delay the stance he would normally get at 4th lv to 6th lv instead (in keeping with the trend of getting a new stance at even-levels like 10 and 16). Likewise, perhaps his 4th maneuver readied at 4th lv ought to be delayed to 5th lv as well, in keeping with the pattern of accruing a new readied slot every 5 warblade lvs.
Same for crusader, who can never get a 8th lv stance, and getting new stances at lv8 and 14 are just wonky. Perhaps delay them to 5, 9 and 15 instead, but could any provisions be made for devoted defender's 6th lv stances?
Swordsage also suffers a similar problem, where his stance at lv14 should be delayed to lv15 instead (otherwise, you have to wait until lv20 or waste another feat).
Some maneuvers also appear confusing. It is no small knowledge that iron heart surge is one of the top offenders, because its vague wording allows it to affect virtually anything, from AMFs to epic spells, even hunger/thirst. Yet, you can't remove the hold-person spell on you because you can't move.
Divine surge seems a little too strong for its level, and its flavour suggests that it is supposed to have some sort of drawback which was not reflected for some reason. Wolf-fang strike sound incomplete (in that it does not seem to entirely address the benefits/penalties you get when you TWF). These are just a few which come to mind at the moment.
Others just plain weird. Elder mountain hammer not having any prereqs? Not necessarily a mistake, but still...
Or do you all want to chip in which your own erratum as well?
