The battle royale system is great for action junkies. Tends to be a more... Forgiving game too. Because each game lasts just 10 minutes on average, things are moving at the rapid pace, and I see a lot fewer occurrence of ping spamming. Sure, the afkers are still there... But at least you can surrender the moment the game tags them as having left the game, so that's less time wasted for you. Of course, the shorter games also means you have to put up with a lot less if you're stuck with a lousy teammate. Or are having a poor run yourself. Which can happen quite a bit in battle royale because a character is chosen at RANDOM each time you play.
Sure, the best players would have mastered every character, every skill... But for everyone else, there's bound to be characters you've not tried extensively, characters you're not good at, or haven't even the slightest idea what equipment to buy for.
Over time though, as you play more rounds of battle royale, you will learn the skills of each character, as well as what equipment to build for it. Weapon, crystal, or hybrid? Which skill do you max first? Which skill do you not max out? All these will come over time. (Or, you can be hard working and do some research, read some guides.)
Bear in mind that battle royale is a vastly different beast from casual or ranked mode though.
Some key differences in battle royale:
1) There is no jungle, it's all blocked off... You fight only in the lane.
For now, I find getting an iron guard contract at the start extremely useful. It'll no longer be needed once the summer update rolls around and the 'ambient gold' system is put into place though (starting 22 June 2016). But for the next few days, I'll still be buying iron guard contracts. That way, you get some gold regardless of who made the last hit. And in vainglory, gold is everything.
So you'd definitely want to optimise your build according. Remember, everything is fast paced. Speed is the key.
2) You start off at level 4, with 2000 gold.
This means that you'll have a nice set of skills to start off with, as well a plenty of gold to buy equipment. Once you get into 'standby mode' in the game, buy all the equipment you need. Don't bother adding the skills till you are done with selecting your equipment and start running out into the field. With just 10 seconds and 2000 gold, there's hardly enough time to spend all your gold before the game starts, especially if you're not extremely familiar with that hero. You'll want to spend those 10 seconds of prep time wisely and get out of the base ASAP.
That said, often times you'll see teammates and enemy heroes alike take a while to 'appear' before they get to the lane. Don't be so quick to label them as afkers yet... They might just be taking some times to figure out their hero and what they need to buy. Great news if the enemy team is no where to be found and all your teammates are already out in the lane and whacking mobs. See if you can hit the first turret a little before the opposing team shows up!
3) You can't get back into the base and shop unless you die
Yup, that's right. The only way to head back to the base is if you die. No teleporting back, no point running back because there's a barrier stopping you from heading back. And you can't use the darn shop outside the barrier.
So what does that mean?
One. You can't heal up if you don't have any healing equipment/skill/items. Good news is that you heal way faster than in casual/ranked games though. But still... It's a good idea to buy some potions if you have the spare cash after your initial equipment purchase. Or maybe you'll want to just stock up some potions before buying the other equipment. Unless you're one of those who have planned out exactly how you want to spend that 2k gold.... Me? I have a target set of equipment to get and I keep buying till my gold runs out...
Two. The only way to move is forward. You either kill them, or die trying. Or, you can hang back a little to heal up.
4) You gain gold and heal up much faster.
You get 15 gold per tick, and heal 4% of your missing HP when you're not in combat. Exp gain, energy regen... Pretty much everything is faster. Oh, minions give 2x gold too. All that for a fast game for battle fiends and impatient players.
I've uploaded a bunch of my gameplay videos. Not that I'm any good... But because hey... Why not?
Check out my youtube channel if you like. I'll keep doing this and perhaps someday I'll get good... :P
