Finally BF4 gets massive balance patch. Now I have covered most of this in my earlier post http://linustechtips.com/main/topic/108970-my-thoughts-on-battlefield-4-jan-30th-and-upcoming-patches/ won't comment on same things. There are several things in this patch that I have opinion and I hadn't commented on last time, so here goes.

This is only my opinion. I'll quote changes and give my thoughts on them. You can check whole thing in here http://battlelog.battlefield.com/bf4/forum/threadview/2955065226155386316/

General fixes

The most important things. Wait, what?

-Tweaked the speed, dispersion, and re-arm duration of the IFV and MBT projectiles

Into what, I ask...

-Fix for an issue on Silk Road where players could deform the terrain to create a big, water-filled hole

Sounds fun. Was there problem....?

-Fix for an exploit that would allow players to shoot two tank shells with not enough delay between shots

You can "rapid fire" shells without it being problem. But I've seen few times tanks with too fast firing. And when you don't have it, its annoying.

-Fixed a bug where red laser dots would get stuck on textures

-Fixed a bug where the enemy health always displayed as full in the kill-cam

Minor things but welcome ones. Last one particularly. I hate when firing half of clip into someone and they seems to survive without hits.

-Improved boat physics and handling, including implementation of a system that lets players push stuck boats back in the water

This sounds interesting. I like the part where you push boats back to water. No more waiting squadmate to do so with another boat. If only they would fix that same thing on tanks and apcs.

Spectator mode

I don't use this feature much and so won't paste anything. Overall there is some good and imo some not so good changes. Since spectating is mostly used for casting matches I feel that DICE has focused more towards general pubbers with these changes.

Grenade balances

I didn't cover these before and there isn't much to cover. Just this:

-Reduced the visual and audio effect for the detonation of the V40 Mini to highlight its smaller blast when compared to other grenades. Decreased the maximum damage from 80 to 60, and decreased the range at which maximum damage is applied.

For now minis have been almost better than M67. Huge change. Makes Metro fun again. Or more fun than it was. Or not.

Pistols

Last time I didn't have anything to say on these. Now I have something.

-Increased the close range damage of the M1911, QSZ-92, FN57, CZ-75 and COMPACT 45.

Good thing. I use QSZ-92 atm and I like it. Its like M9 of BF4 with current M9 being shadow of BF3 version.
