I realized that Lazarus works extremely good with a good team that coordinates and plans ahead.
An ESL team (forgot their name) runs Lazarus as their medic, and guess how they destroy multiple top ranks and ESL monsters? They leave Lazarus outside the dome while trapper, assault, and support go in and punish the monster and as soon as one dies the dome will be taken out while pressure is on the monster so it won’t eat the body. Next thing you know the dead hunter is revived because the monster couldn’t do anything. This strategy has even happened to me and it is extremely exhausting to plan what you must do, because Lazarus at that point just messes with your head.
The personal healing burst is actually for personal use and for times when chasing the monster but not in combat. The game even says that he isn’t a medic, but a Lazarus man which makes total sense. If he’s in the dome then yeah, consider your team a loss because he sucks at that point.
