The kunai cube patch I would say is the size of ROI.

ROI is nowhere near the same size in terms of content as RoS.
And as for other games
guild wars 2 also comes to mind, they have expansions for sale and
micro transactions but they also have large free content patches that include things like raids.
Path of exile has plenty of large content patches all for free and has
a very fair microtransaction shop.
Thinking about it,
gta5 also qualifies, those heists were some of the best content I've played in a video game and they have all come free.
WoW also gets free patches on par with the size of TTK, you could argue that it requires a subscription but at the same time WoW actually hosts dedicated servers and has 24/7 live customer service which Destiny lacks completely.
