Rattlesnake maybe one of the ship that need the most skill point in highsec. tho, for new players, its also excellent ship.
It got role bonus as much as lv5 dominix with just lv 3 battleship skills. which is what new players should use. Just
Just bring one with sentry drones and LMJD, go to apakane and do lv4 SoE missions.
How to play: This Rattlesnake gonna want to jump around with LMJD, shoot stuff from 90km away with warden. Without getting any shot.
At Apanake, SoE will rarely gives Gurista opponent. The only faction that can touch this ship.
Quite cheap too, a hull with just T1 modules will get the job done. And just need couple of weeks to train into it. You can improve stuff as you skill up.
About the fitting, its all depend on your fitting skill. You might want to tinker a bit, this is EVE, tinker with ship fitting is fun. You gonna need sentry, and LMJD since its the core strategy. You gonna need to increase drone control range and lock range. Pick arbalest cruiser missile launcher, but it wont be your main damage dealer.
double Invuls for the only tank you need. you dont need shield booster, when a frigate or cruiser got you, pull the sentries and press the LMJD again. Those invuls just to buy the time needed for LMJD cooldown.
You might want to add some PWG and CPU modules depend on your fitting skill.
Quite cheap and efficient as new player, since you doesnt need to over commit months and months skill training to fly marauder to wipe clean a LV4 in Apanake.
