So, for anyone wondering, if increase of replys is any good.

Yes and no.

No, because even with the added conversations of the event I now have reached the point, where I have 1 reply left and cannot use it. With a 2 reply limit. In some hours new ones will unlock.

Yes, because the other ruby options are not thaaaaat good, to have an impact, if you do less of those because you upgraded the limit.
