No prob. I gave up on KB/Mouse and just use an xbox 360 controller. My hand joints are too old to keep pressing the left mouse button.
Yeah I gave up on KB/M because it was very poorly optimized for the PC port on release. I am not sure if it ever got better...bot the controls and menus were more or less designed with an analog stick and only a few buttons in mind, unfortunately.
I guess builds depend on your player character class, but a few tips that I found to universally hold through most of the game (not sure if patches/updates have changed since I last played)
--crafting can be great, overpowered, and also largely unnecessary. My entire playthrough of my shield warrior saw me crafting two or three sets of gear throughout. High-end crafted stuff lasts through several levels. Honestly, you make it through pretty easily by just equipping the unique purple stuff that you find. Much of it is that good. Certainly for your party members.
--At least one mage in your party, 2 can make life super easy. One, or all of your mages, should invest heavily in the barrier tree. There is no healing outside of limited potions shared by party, so damage mitigation is the key, and that tree is essential for all mages. I liked to build my mages as barrier, and then focus on element. The specializations midway through the game are a different story, and tend to be fairly OP for any class (especially the ranged thief specialization, and the mele mage, whatever that was called).
--I think several fixes have been implemented for party AI when it comes to skills, such as the warrior charge, bullrush or somesuch, where you would notice your tank teammate rushing well out of the fight and generally fucking you all up when the dragon turns their attention to your tasty DPS thief. I found that the most successful parties feature one super tank warrior (high fortify and taunt build--I like the shield classes which also add some stun), a ranged thief (early game, dual dagger is really good; late game, the ranged specialization puts out the highest damage in the game...assuming that is still the case) for DPS and either two mages for barrier/damage, or a second frontline warrior or thief. whatever feels right.
Frontline can get crowded in this game, so oftentimes more than one individual up there whacking on your target(s) can be very inefficient. Perhaps hitboxes were fixed, though, and the AI once had problems orienting your mele party members properly.
Gold is more or less useless. Just sell nearly everything you pick up, that you don't want to equip, and you will find that there are maybe a handful of things worth purchasing from merchants throughout. Really, it's about the high-end crafting schematics that you find in the late level areas.
There isn't much direction as to how you should progress, and each main region is level capped, so you can find yourself woefully underleveled or embarrassingly overleveled for certain areas, depending on when you choose to unlock them. I think the order is something like Swamp/Stormcoast -> desert area (forget name of this one) -> Elven battleground -> forest area -> En champdulione deux frenchy name (the snowy area) -> Hissing Wastes (the nighttime desert area--the name that I actually remember).
Also feel free to venture out of the Hinterlands before finishing up everything. It is a large area and can really drag you down if you are feeling ultracompletionist early on. Some regions are rather high-leveled there, anyway, so it encourages you to get out and see the world a bit.
Power points are rather useless. The collection quests for crafting items in each map are infinite, so if you keep doing those, you will have some 50x power points than you could ever possibly use. Those missions are just there for you to make sure you can unlock map areas if you are feeling desperate.
As for the party attributes that you unlock from your advisors through the war table, you first want to get the extra potion slot on your party belt, and there are a few others that I forget, which are really useful early on. Ignore the ones from the fancy lady about traders coming in for rare and unique items. They just give you a one-time dump of some detritus that you will likely never use...again, unless this has changed.
