you realize that the sam lb is the slowest to charge? in the same time a sam get 1 lb the other can have 1-1.5 lb.... that not a small counter part. plus someone say, yes but it do 24k damage in line. true, but let look at the lb of the summoner. you have 18k when you summon it in a super large area + another attack at 12k and while is not enough the summon attack alone every 2.5 sec at 6k all of this for 20 sec... without forget the fact that your basic attack become a 6k damage instead of 4k in terms of damage it's far over this sole 24k in line.

if not enough let's check other lb like the warrior, that block guard, make you immune at most of the CC, increase your run speed, increase your hp max by 20% while healing you of this 20% and finally give you access to an attack that you can spam at 12k.

not enough fine, dragoon, you become invulnerable while removing root , half sleep and snare for 5sec until you decide where you land the attack that will deal in a good area (not massive but big enough for be really strong) 20k damage +50% if the target is at less of 5 yalms of the target of your lb... for a good 30k. yes it can't os, but it give you some an incredible survivability and damage wise if no one have hit the sam is still far stronger than the sam lb.

every lb well used can simply destroy a game. some more than other... but in the end it more about how you use them that count. even if i feel that the warrior lb give too much and need to be addressed since you can still use the skill for get 100% of the damage as healing meaning the warrior can deal 12k while healing 12k for 10 second... while being litterally unstoppable.
