Traditionally (or lately, I guess I should say) I play as a recon. Most maps have nice open bottom areas where I can hide, and charge up my Callahan. I also carry a BTB and DA for close encounters, but the majority of my damage is gun based. Callahan has great range, so from the bottom, it's a complete suprise (TWSS).

If a group is clustered on a point, I will cloak, sneak in and double swing the DA. Once done, I GTFO, ideally drawing them off the point, and backtrack to cap it.

1. My usual is don't use boost until the enemy runs out then, charge at them unrelentlessly until they die.
2. When I rage, (I tend to do it at the last minute of a game) I charge at them, and ; kinda like tmdals hit enemes before the even stop to hit you. I twirl, keeping myself stationary, putting off the enemy and dodging, and chain flourish and hammer combos together by midstepping a lot.(for some reason it doesn't really work on my guildmates)
3. Don't use boost unless you see someone vunerable or are being attackes. I sense people before they come, and hit em while boosting or counterattack.

I know all here have likely already seen them, but I highly recommend Blueflood's videos for some excellent examples of different LD strategies, and particularly in regard to the importance of teamwork (or lack thereof in random) and managing capture points.

1) Fight only when it is more productive than capping.
2) Heal when on low health and no enemy is around.
3) Stall fights I cannot win.
4) Delaying cap for more than 10 seconds > preventing personal death.
5) Change loadouts/class when current one is clearly not working.
6) Change attack patterns as frequently as possible.
7) Spam AT so people feel they have a legitimate reason to rage.

Usually send out a high def/res/hp guardian (unequip the weapon) to tank for damage while recon shoots past and gets some damage. If it's really needed, give them a brave, quick sword, too.

I also like to equip my recons with some kind of lightning weapon, since of all elements, they gives about a extra crit and skill% chance of dual strike, if paired up with someone else.
Sometimes, if the recon's skill/speed is high enough for the people attacking the guardian to not matter, it might activate luna, reducing their targets' defense. People don't place too much importance on its effect, but remember, any help is good help.

As far as weapons go, Elstorm Driver (charge) has a pretty good critical chance. I've OHKO'd a full health guardian with its charge with only VH damage bonus. He was pretty mad after losing his guardian that way and took a striker out after me, not that that really helped since my recon was higher level anyway.

Sometimes I'll have a Chaos bombmage with Stagger to reduce enemy speed within a certain range. Paired up with an assassin, they tend to be pretty effective in RLD, since they tend to draw aggro.

Pairing up a guardian general with a good swordmaster striker or two can really increase muscle value in your team especially with their defense aura, but they also do make pretty good bait for snipers, too.

...recently bought FE:A l0ol, couldn't help it.

1. I'm usually start with Striker so I can cap first point faster.
2. I'm bad at Striker, so I just DA/GF combo! Very effective.
3. If I'm dead, I change to Recon (I pretty good at Recon).
4. Give them Deathmark and see they run like crazy is funny.
5. I don't do DA/GF combo when going Recon unless I'm doing ambush with 3 people standing at cap point.
6. I thing get rough, turn AA
7. Spam polaris + hammer when fighting skilled player.
8. Going striker again when match almost end.
9. See match result and click play again.
10. Wait 10 minute on loding.
11. Repeat.

I created a shock mist barrier that acted like an artificial shield. The other team wouldn't pass, and we had about three really good strikers and a guardian keeping the heat off me. A different point in the same battle, I dropped down voltaic tempest bombs like there was no tomorrow on the frontlines protected by a guardian shield.

Oh! A different game I was in recently was amazing as we won by one point, and there were only two strikers in total - one on each team. Two guardians work better than one might think.

Also, always have a Guile's theme playing. You will do better.
