After some investigation: Yes you are right. We removed both the ‘Great Combo’ and ‘Trend Match’ bonuses with the Steam release update. Instead we increased the bonus that a ‘New Combo’ provides. This was part of a balancing overhaul.
We didn’t like the fact that you could just spam great combos to get quick XP. The new change encourages more experimentation.
but what about ‘trend match’? that’s pretty much RNG anyway, and if you removed the exp bonus on trend matching, you might as well remove trends all together because now there is no encouragement to attempt them.
I was always trying to get ‘strange combo’ matches, because I still didn’t know them, but I suppose there is no point, now.
