Ending the Parry debate once and for all

It could just as easily mean they account for tank dps in general - even a vit tank will be producing non-negligible dps.

The actual, exact words used by Yoshi-P is this:

レイド攻略の際には一般の腕のプレーヤーがクリアできるであろうアイテムレベルを想定しています。その想定アイテムレベルに到達した4DPSとタンクの基礎DPSを合算して、さらに10％から15％のしきい値を下げてクリア想定を作っています。ヒーラーのDPSは計算に入れていません。

We take the item level at which we think the average-skilled player should be able to clear the content, use the dps that can be produced from that item level, take the sum of 4DPS and tank's base dps, then lower that by 10-15% to be the clear threshold. Healer dps is not counted.

So they account for the base tank dps, which some people seem to take to mean full STR build plus STR accessories and tanking in the dps stance.
