Is it worth the time to do all the quest objectives?

Look at it this way.

Grind PvP with the same old decks playing people with likely similair decks for hours and days to get 30/30/60 gold.

Create unique decks for situations (I'm thinking no more than 5 minutes to craft a deck for a particular scenario, that's assuming you don't craft one that can take care of multiple scenarios [Jace is very good for this]) and get 15 Gold per objective. I found it pretty easily to get at least 4-5 objectives done per day, and my time is rather restricted with me taking care of the kids and whatnot.

So, boring grinding for 120 gold per week that takes a lot of time

Or

Creative playing for (at 3 objectives per day) 315 gold per week for little time invested

I would say it's worth it.

Just a suggestion. If you are playing pvp for gold, then you are going to hit the point where you can't play because it will put you at 16th or above. Use this time to craft a deck and get objectives out of the way.

Also, suggestions for objectives:

Commander: Hangerback Walker/Any card that summons thoptors. Each thoptor counts as a creature summoned, so summoning hangerback and killing him (Liliana/Chandra?) will be enough to beat the objective

Destory/Sacrifice X creatures: With the current bug, sacrifice actually only counts when an opponents creature is destoryed - Chandra (Burn spells), Liliana (Death spells), Gideon (Guardian of Meletis + 3rd Ability buff and 1st ability buff, followed by supports and 2nd Ability buffs for a near indestructible wall that can't attack)

Win in X turns: Nissa (only save up for 2nd ability). Can take a lot of tries at chapter 3, but a good starting hand with a near epic first turn cascade or match 5 will get the job done

Cast X spells: Chandra (Burn), Jace (Bounce/Turn to frog/Drain mana)

Survive with x life: Use Gideon and immediately quit the game. He will end up with low life. Start a new game, and cancel all cards until the enemy hits you once to put you under. Then summon your whole hand and use first strike or defenders to beast your way to victory

Take x damage: Orbs of warding or Lifelink. It doesn't matter how much life you have, only that at some point you took that much damage.

Cast X supports: Jace (control the game with claustrophobia and bounce while waiting for supports), Gideon (starfield of nyx, cheap supports, focus on destroying your own supports to recast them with nyx)

Nice! Its been awhile since I had to do it but

Sacrifice: Jace (Scaab Goliath-use him to destory himself, turn to frog - again, on your own creature since it counts as a kill), Chandra (Burn your own defensite creatures if they don't die destroying any oppositional creatures, Nissa (Goggles + Aurora), Gideon (Murder investigation + Soldier support that gives defender + Brawlers), Liliana (Unholy hunger + any creatures/spells that make you sacrifice a creature)

I'm just thinking is it worth the time and effort to do the objectives for the yellow crystals?

Meh. It was fun to try to squeeze them all in before they switched the 2nd rewards from an awesome 8 to a sadly worthless 250 (seriously - one QB is worth more and much easier), but since the change it just doesn't seem worth it. Sometimes I cherry pick a few of the 15 ones if I'm close to a big box, just to speed it up, but the rewards are generally so bad it's hard to get motivated. But, as someone else said, if you enjoy playing then you enjoy playing, and the rewards are just icing. I wish they'd change it back to though. Part of me is delaying on getting the rewards in case they do.

As for which PW is best, I tend to use red a lot so I find her pretty good at getting a lot of them. She can control the board with no creatures out fairly well, which allows you to let rounds pass, kill enemy creatures, or summon your own and then kill them immediately without killing the opponent. Technically she can also beat herself up really easily too, but allowing the opponent to hit you is still easier. She can't heal, though, so you just have to have more HP than you need to start with when the goal is to take damage.
