Wrong. This limitation makes no sense and some buffs due long casting time, like an full round was meant to be used before combat. If you are that dependent to buffs, you should lower the difficulty or see what you are doing wrong. And keep in mind hat supernatural powers are far more deadly on pfk. Imagine entering an encounter with wild hunt without time to cast freedom of movement and in the first round, the guy who can cast it fail his save.... You lost.
Well, there were some better alternatives mentioned earlier in the thread such as long buffs being concentration things - cast once and the character keeps it up without having to recast them. Would introduce an interesting mechanic where you have to pick and choose which buffs you want to have up as you don't have enough concentration for everything. And... I'm not quite sure I see a problem with that encounter with wild hunt - imagine instead being the monsters and being suddenly jumped but bunch of really buffed up adventurers.
The problem I'm really trying to solve is the amount of clicks. Yes maybe I don't have to cast everything. But even then I have a front line of 3 maguses. Each needs to cast Shield, Mirror Image, Blur, Arcane Weapon and Expeditious Retreat as a minimum. Skip the 1st 3 and I'm eating damage every fight, skip the last one and I'm suffering in Turn Based mode unless haste is on. Not casting Arcane weapon is just silly as a Magus, but at least it seems to be instant cast. All of these a 1 min per level. That's 15 clicks and pauses already with just their self buffs. Add Mirror Image + Expeditious Retreat for Octavia and some health buffs for her + stuff like Bless and that Communal Poison block and you're up to 20. Freedom of Movement is another 3+. Etc. They just need to start respecting the player's time.
